Bukhari

Hadith Commentary:
On the occasion of the Farewell Pilgrimage (Hajjat al-Wada‘), after completing the rites of Hajj, the Messenger of Allah (sallallahu alayhi wa sallam) had his blessed head shaved, and for those Companions who had their heads shaved, he supplicated for mercy and grace for them three times, while for those who had their hair cut short, he supplicated only once.

There is no evidence that the Messenger of Allah (sallallahu alayhi wa sallam) ever had his head shaved except during Hajj and ‘Umrah; rather, he kept his hair with great honor and respect.

His hair would sometimes reach his ears and sometimes be level with his neck.

When it grew long, his hair would take the form of plaits.

Since these ahadith mention the Farewell Pilgrimage (Hajjat al-Wada‘), Imam Bukhari (rahimahullah) has mentioned them here.

Hadith Commentary:
It is understood that shaving the head or cutting the hair is also one of the acts of Hajj.

Hadith Commentary:
(1)
Abdullah ibn Umar (radi Allahu anhu) intended to perform Hajj in the year when Hajjaj ibn Yusuf launched a military campaign against Abdullah ibn Zubair (radi Allahu anhu). Ibn Umar (radi Allahu anhu) entered into the state of ihram, and continued in it until the tenth of Dhu al-Hijjah, when he offered the sacrifice and shaved his head. Then he said that the Messenger of Allah (sallallahu alayhi wa sallam) had done the same during his Hajj.
(Sahih Muslim, Book of Hajj, Hadith: 2992(1230))

(2)
From this hadith, Imam Bukhari (rahimahullah) has established the permissibility of shaving the head when exiting the state of ihram, while in the chapter heading he also mentions trimming the hair. Accordingly, in some narrations it is mentioned that the Prophet (sallallahu alayhi wa sallam) and his noble Companions (radi Allahu anhum) shaved their heads, and some individuals trimmed their hair.
(Sahih al-Bukhari, Book of Expeditions, Hadith: 4411)
However, it is not permissible for women to shave their heads; rather, they should take a few hairs from their braid. Thus, it is narrated from Ibn Abbas (radi Allahu anhu) that the Messenger of Allah (sallallahu alayhi wa sallam) said:
“For women, there is no shaving of the head, only trimming.”
(Sunan Abi Dawud, Book of Rituals, Hadith: 1984)
In any case, at the conclusion of Hajj or Umrah, shaving the head is superior for men, and trimming is permissible, as will be made clear in the forthcoming ahadith.

Hadith Commentary: Benefits and Issues: Abu Hurairah radi Allahu anhu accepted Islam in 7 AH, and he mentioned the prostration (sajdah) of two of the detailed (mufassal) surahs, which is evidence that prostration should also be performed in these surahs.

According to Imam Malik rahimahullah, there are eleven prostrations in the Noble Qur’an. He does not consider there to be a prostration in Surah Sad, Surah Najm, Surah Inshiqaq, and Surah Iqra.

According to Imam Shafi’i rahimahullah, there are fourteen prostrations, and he also does not consider the prostration of Surah Sad, but he considers there to be two prostrations in Surah Hajj.

According to Imam Abu Hanifah rahimahullah, there are also fourteen prostrations; he considers the prostration of Surah Sad, and he considers there to be one prostration in Surah Hajj.

According to Imam Ahmad rahimahullah and the hadith scholars (muhaddithin), there are fifteen prostrations; they accept all of them.
