Bukhari

Hadith Commentary:
The narration of Zubaidi has been recorded by Imam Bukhari rahimahullah in his Tarikh and by Tabarani in his Mu’jam Kabir.
Imam Bukhari’s purpose in mentioning this is to show that there is a difference among the narrators regarding the shaykh of Zuhri.
Yunus and ‘Uqayl have mentioned Haytham ibn Abi Sinan, while Zubaidi has mentioned Sa’id ibn al-Musayyib and A’raj. It is possible that Zuhri heard this hadith from all three of them. Hafiz has said that, according to Imam Bukhari, the first method is preferable, because both Yunus and ‘Uqayl have unanimously considered Haytham to be Zuhri’s shaykh (Wahidi).
From this hadith, it is established that mentioning the blessed life (sirah) of the Messenger of Allah sallallahu alayhi wa sallam in prose or poetry in gatherings of admonition is correct and permissible.
In connection with the sirah, mentioning the blessed birth and the pure life events of the Prophet sallallahu alayhi wa sallam is a cause for increase in faith. However, the holding of the customary mawlid gatherings is not established by any Shar’i evidence.
In the era of the Companions, the Followers, the Followers of the Followers, the Mujtahid Imams, and all the noble hadith scholars, there is not even a trace or mention of such gatherings.
A full six hundred years passed, and the Islamic world was not even familiar with the name of the mawlid gathering.
It is stated in Tarikh Ibn Khallikan that the first originator of this gathering was a king named Abu Sa’id Muzhaffar al-Din, who was the ruler of a city called Irbil near Mosul.
The firmly grounded scholars have opposed this newly invented gathering from that very time.
But, alas, even today, self-styled devotees of the Messenger of Allah sallallahu alayhi wa sallam hold such gatherings with great pomp, in which extremely fabricated and incorrect narrations are mentioned, special arrangements are made for illumination and distribution of sweets, and people stand and recite salutations (salat wa salam) with the belief that the blessed soul of the Prophet sallallahu alayhi wa sallam himself has arrived in the gathering.
All these matters are incorrect and baseless, and engaging in them necessarily leads to the commission of innovation (bid‘ah).
The Messenger of Allah sallallahu alayhi wa sallam has clearly stated: “Whoever introduces into our matter that which is not from it, it is rejected.”
Whoever invents something new in our religion for which there is no proof from the Shar’i evidences, it is rejected.

Hadith Commentary:
(1)
The relevance to the title is found in these words:
"Your side stays away from the bed."
Because this can only happen through staying awake at night.
The Messenger of Allah (sallallahu alayhi wa sallam) would wake up at night for prayer, remembrance (dhikr), and recitation of the Qur'an. Thus, the poet has alluded to this statement of Allah, the Exalted:
﴿تَتَجَافَىٰ جُنُوبُهُمْ عَنِ الْمَضَاجِعِ يَدْعُونَ رَبَّهُمْ خَوْفًا وَطَمَعًا﴾ ()
"Their sides forsake their beds; they call upon their Lord in fear and hope."
From this, it is understood that good poetry, like good speech, is praiseworthy.

The corroboration (mutaba‘ah) of ‘Aqil has been narrated by Imam Tabarani in al-Mu‘jam al-Kabir with his connected chain, and the suspended narration (ta‘liq) of Zubaidi has been mentioned by Imam Bukhari (rahimahullah) in al-Tarikh al-Saghir and by Imam Tabarani in al-Mu‘jam al-Kabir with a connected chain.
