Bukhari

Hadith Commentary:

Hafiz (rahimahullah) said:
According to some, this is absolutely prohibited.
Some have said that this prohibition was only during his (sallallahu alayhi wa sallam) lifetime.
Some have said that combining the names is prohibited, i.e., naming someone Muhammad Abu al-Qasim.
The second opinion is preferred.

Hadith Commentary:
1.
Kunyah is derived from the word kinaayah (allusion).
By this is meant a word that does not explicitly indicate a person’s identity, but can refer to them indirectly.
In the Arabic language, a kunyah is that which is preceded by "Abu" (father of) or "Umm" (mother of).
Among the Arabs, adopting a kunyah was well-known.
Some people were known by their kunyah and their actual name was unfamiliar, such as:
Abu Talib and Abu Lahab, etc.
And for some, their given name was predominant and their kunyah was little known, for example:
‘Umar radi Allahu anhu—his kunyah, Abu Hafs, is not well known.
In any case, kunyah, name, and laqab (title) are all identifiers by which a person’s identity is recognized.
2.
The kunyah of the Messenger of Allah sallallahu alayhi wa sallam was Abu al-Qasim.
Two reasons are mentioned for this:
a.
His noble son’s name was Qasim, so he became well known by this kunyah.
b.
He used to distribute Allah’s wealth among the people; thus, the Prophet sallallahu alayhi wa sallam said:
“Allah gives, and I distribute.”
(al-Mustadrak ‘ala al-Sahihayn: 2/660, Dar al-Kutub al-‘Ilmiyyah, Beirut edition)
On this basis, he was called Abu al-Qasim.
3.
In the hadiths, the prohibition regarding this was specific to his lifetime.
Other related discussions will be mentioned in the Book of Manners (Kitab al-Adab),
by the permission of Allah Ta‘ala.

Hadith Commentary:
This is among the unique characteristics of the Prophet sallallahu alayhi wa sallam, that Satan cannot appear in his form, so that he cannot falsely claim, in a dream, to be the Prophet and thereby lie to anyone using his name.
Whoever sees the Prophet sallallahu alayhi wa sallam in a dream certainly comes to know that he has indeed seen the Prophet sallallahu alayhi wa sallam himself, and this matter becomes apparent to the one who sees him in one way or another.
The warning of Hellfire is for the one who, without reason, falsely claims, "I saw you (the Prophet) in a dream," or fabricates a lie and attributes it to him.
Thus, those who fabricate false ahadith are living inhabitants of Hellfire.
May Allah protect us from them. Ameen.

Hadith Commentary:
(1)
Some scholars are of the opinion that a child should not be named Muhammad. They have presented this narration as evidence. The Messenger of Allah (sallallahu alayhi wa sallam) said:
"You name your children Muhammad and then you abuse them."
(Musnad al-Bazzar: 318/2, no. 6895)
Similarly, Umar (radi Allahu anhu) during his caliphate issued an official order that children should not be named after any prophet, and on this basis he changed the names of some children. However, this position is questionable because the narration presented is not authentic, and it is established that Umar (radi Allahu anhu) retracted this position. When he learned that the Messenger of Allah (sallallahu alayhi wa sallam) himself named a son of Abu Talhah as Muhammad.
(al-Mu'jam al-Kabir by al-Tabarani: 242/19, no. 544, and Fath al-Bari: 702/10)
(2)
Imam al-Bukhari (rahimahullah) has established from the aforementioned narrations that there is no prohibition in naming children after the prophets (alayhim assalam), and the Messenger of Allah (sallallahu alayhi wa sallam) himself granted permission to name children after his own name.
And Allah knows best.

Hadith Commentary:
During his blessed lifetime, this prohibition was in place so that there would be no confusion.

Explanation:
The purpose of these continuous ahadith is that people should not attribute false statements to the Messenger of Allah (sallallahu alayhi wa sallam) and thereby mislead creation in this world. These ahadith themselves indicate that, in general, the corpus of Prophetic traditions has remained protected from the tampering of corrupt individuals, and whatever ahadith people fabricated on their own, the scholars of hadith separated them from the authentic ahadith.

Similarly, the Prophet (sallallahu alayhi wa sallam) also made it clear that if someone sees me in a dream, that vision must also be correct, because in a dream, Shaytan cannot appear in the form of the Messenger of Allah (sallallahu alayhi wa sallam).

To distinguish between fabricated (mawdu‘) and authentic (sahih) ahadith, Allah the Exalted created the community of hadith scholars (muhaddithin), especially such great figures of the ummah as Imam Bukhari and Muslim (rahimahullah). They served this discipline in such a way that no parallel can be found in previous communities; they invented the science of narrators (ilm al-rijal) and the principles of criticism and validation (jarh wa ta‘dil) such that the Muslim ummah will take pride in them until the Day of Judgment. Yet, it is a great regret that in this fourteenth century, some such prejudiced, rigid imitators (muqallid) have emerged who themselves declare these elders to be non-jurists (ghayr-faqih) and unreliable. Such people, merely in support of their supposed schools of blind following (taqlid), seek to cast doubt upon the corpus of Prophetic traditions and thereby undermine the very roots of Islam. May Allah grant them sound understanding. Amin. It is a fact that those who call Imam Bukhari (rahimahullah) a non-jurist and overly sensitive are themselves lacking in understanding, and by uttering such big words with small minds, they only display their own lack of intelligence. In discussing this matter, the author of Anwar al-Bari, in repeatedly referring to the Ahl al-Hadith community with the term “the non-muqallid group” in a tone of sarcasm and insult, has acted in a manner highly worthy of condemnation. But this is the effect of rigid taqlid: such prejudiced individuals have insulted and belittled many great figures of the ummah. This has been ongoing since ancient times. The opponents did not even spare the Companions; they declared Abu Hurayrah, Uqbah ibn Amir, Anas ibn Malik, and others (radi Allahu anhum) to be non-jurists.

Hadith Commentary:
➊
To fabricate a lie against the Messenger of Allah sallallahu alayhi wa sallam is absolutely forbidden in every circumstance, whether it pertains to wakefulness or to sleep.
Lying in sleep means that a person claims, without having seen, that he saw the Prophet sallallahu alayhi wa sallam in a dream.
Firstly, lying is not permissible in any matter whatsoever.
If it pertains to the noble person of the Messenger of Allah sallallahu alayhi wa sallam, then its gravity and prohibition increase even more.
It is mentioned in the hadiths that on the Day of Resurrection, those who narrate false dreams will be made to tie together two grains of barley and told to do so.
(May Allah protect us from this.)
The blessing of seeing the Messenger of Allah sallallahu alayhi wa sallam in a dream can only be considered auspicious if the appearance seen in the dream matches the noble description of him found in the books of hadith.
A reliable book regarding his noble appearance is "Al-Rasul Ka'annaka Tarahu," which is very beneficial. Its Urdu translation, under the title "Aina-e-Jamal-e-Nubuwwat," has been published by Darussalam, authored by the undersigned.

➋
Imam Bukhari rahimahullah has observed a particular order in presenting these hadiths:
The first hadith is narrated from Ali radi Allahu anhu, in which the gravity of lying against the Messenger of Allah sallallahu alayhi wa sallam is described, and this is exactly in accordance with the chapter heading established by Imam Bukhari rahimahullah.
The second hadith is narrated by Zubair radi Allahu anhu, in which it is mentioned how cautious the noble Companions radi Allahu anhum were in transmitting hadith.
The third hadith is from Anas radi Allahu anhu.
In it, the explanation of caution is given: the noble Companions radi Allahu anhum exercised caution in narrating abundantly, but their intention was not to refrain from narrating altogether.
The last hadith, which is narrated from Abu Hurairah radi Allahu anhu, indicates that fabricating a lie against the Messenger of Allah sallallahu alayhi wa sallam is absolutely forbidden in every circumstance, whether it pertains to wakefulness or to sleep.
(Fath al-Bari: 1/268)

Explanation:
1:
There is a difference of opinion among the scholars regarding this matter.
Some say that during the lifetime of the Prophet (sallallahu alayhi wa sallam), this was prohibited,
but after him, it is permissible to take his name and his kunyah (patronymic).
Some say that it is prohibited to combine both together,
while others say that the prohibition pertains only to the kunyah.
The first opinion is the most correct.
(See the next two hadiths)

Benefits and Issues:
It was not permissible to adopt this kunya (patronymic, i.e., "Abu al-Qasim") during the lifetime of the Messenger of Allah (sallallahu alayhi wa sallam), but after him, the scholars have permitted that both his name and kunya may be adopted.
The reason for the prohibition during his life was this incident: Once, the Prophet (sallallahu alayhi wa sallam) was in the marketplace when a man called out "Abu al-Qasim." The Prophet (sallallahu alayhi wa sallam) turned around, but the caller said, "I did not call you; I was calling so-and-so."
After this incident, he (sallallahu alayhi wa sallam) forbade adopting this kunya.
(Fath al-Bari, al-Adab, Hadith 6188. For further details, refer to Fath al-Bari.) The evidences for permissibility will be mentioned in the following chapters.

Benefit:
From this hadith, it is understood that naming someone after the Prophet sallallahu alayhi wa sallam, such as Muhammad, Ahmad, or simply Muhammad or simply Ahmad, is permissible, because their meanings are of praise. However, no one may adopt the kunyah (patronymic) "Abul-Qasim," because if someone adopts this kunyah, there will be a possibility (of confusion). But after the passing of the Prophet sallallahu alayhi wa sallam, it is permissible to adopt the kunyah "Abul-Qasim."
