Bukhari

Hadith Commentary:
Imam Bukhari, may Allah sanctify his secret, is establishing here that it is permissible to bring various types of wealth into the mosque for the purpose of distribution and to distribute them there, just as the Prophet (sallallahu alayhi wa sallam) had the money that came from Bahrain placed in the mosque and then distributed it in the mosque itself.
At times, the Companions who were engaged in agriculture would bring clusters of dates and hang them in the Prophet’s Mosque for the benefit of the Ashab al-Suffah (the People of the Bench).
For this, the words "ṣinwān" and "qunwān" were used, and both of these terms are also found in the Noble Qur’an.
"Ṣinw" refers to those date palms which grow two or three together from a single root.
The narration of Ibrahim ibn Tahman has been transmitted by the Imam (rahimahullah) in a suspended (mu‘allaq) form.
Abu Nu‘aym has narrated it in his Mustakhraj, and Hakim (rahimahullah) has narrated it in his Mustadrak in a connected (mawsul) form.
From Ahmad ibn Hafs, from his father, from Ibrahim ibn Tahman: The treasure that came from Bahrain was one hundred thousand dirhams, which was sent to the noble service of the Prophet (sallallahu alayhi wa sallam) by ‘Ala’ al-Hadrami (radi Allahu anhu), and this was the first tribute (kharaj) that came to you in Madinah Munawwarah. The Prophet (sallallahu alayhi wa sallam) distributed all the money among the Muslims and did not keep even a single coin for his own (noble) self.
As for ‘Abbas (radi Allahu anhu), the Prophet (sallallahu alayhi wa sallam) granted him permission to pick up the money, but neither did he (sallallahu alayhi wa sallam) help him himself, nor did he allow anyone else to help. The purpose of this was so that ‘Abbas (radi Allahu anhu) would understand and not develop excessive greed for worldly wealth.

Hadith Commentary:
1.
There are two parts to the chapter heading established by Imam Bukhari rahimahullah:
© The distribution of wealth in the mosque © The mention of hanging a cluster of dates in the mosque.
The hadith presented in this regard has been narrated in a connected form by Imam Hakim rahimahullah in his Mustadrak. From this, the issue of distributing wealth is established, but there is no mention in it regarding the hanging of a cluster of dates.
The commentator Ibn Battal rahimahullah has considered this an oversight on the part of Imam Bukhari rahimahullah.
(Sharh Ibn Battal: 2/173)
Ibn Teen has attributed it to a lapse of memory by Imam Bukhari rahimahullah.
(Fath al-Bari: 1/668)
However, some commentators have mentioned explanations in accordance with Imam Bukhari rahimahullah’s scholarly approach. Imam Bukhari rahimahullah is making an analogy between hanging a cluster of dates and the distribution of wealth, because in both cases, the matter of keeping wealth in the mosque for those in need is commonly found.
By mentioning it in the chapter heading, Imam Bukhari rahimahullah has alluded to the narration which Awf ibn Malik radi Allahu anhu has reported in these words:
The Messenger of Allah sallallahu alayhi wa sallam once entered the mosque and he had a staff in his hand.
A man had hung a cluster of inferior dates in the mosque.
He (the Prophet) struck that cluster with his staff and said:
“The one who gives charity could have given something better than this in charity.”
(Sunan al-Nasa’i, Zakat, Hadith: 2495)
Since this narration did not meet Imam Bukhari rahimahullah’s criteria, he merely alluded to it in the chapter heading.
(Fath al-Bari: 1/669)
Although this narration does not mention a cluster of dates, Imam Thabit ibn Hazm Andalusi rahimahullah has stated in Dalail fi Gharib al-Hadith, along with this narration, that when the Prophet sallallahu alayhi wa sallam entered, he saw clusters of dates hanging in the mosque, because he had ordered that they be hung on every wall so that those who had nothing to eat could eat from them.
From this, it is understood that in the original narrations, there was mention of hanging clusters of dates in the mosque, to which Imam Bukhari rahimahullah has alluded in the chapter heading.
(‘Umdat al-Qari: 3/409)
In any case, from the narration, the issue of distributing wealth in the mosque is established.
As for the ruling of hanging a cluster of dates in the mosque, although it is not in the narration, it is established by analogy from the original narration or from other narrations, as Imam Bukhari rahimahullah has indicated in the chapter heading.

Other narrations show that Alaa ibn Hadrami rahimahullah sent about one hundred thousand dirhams from Bahrain, which had been collected from the inhabitants there as tribute, and this wealth had reached Madinah and was distributed by him.
But from the narration of Jabir radi Allahu anhu, it is understood that the Messenger of Allah sallallahu alayhi wa sallam had promised to give him from the wealth coming from Bahrain, but he passed away before it arrived.
Apparently, there seems to be a contradiction between the two narrations, but in reality, this narration does not contradict the aforementioned hadith, because the wealth used to come every year, and in the year when the Prophet sallallahu alayhi wa sallam promised Jabir radi Allahu anhu, he passed away before the wealth arrived.
(Fath al-Bari: 1/669)
And Allah knows best.

From this, it is understood that every act in the mosque that relates to public welfare is permissible, for example:
Arranging a water supply from which everyone benefits, and similar other acts can be done in the mosque.
It should be noted that wealth may be kept in the mosque for distribution, but it is not permissible to use the mosque as a storehouse.
(Fath al-Bari: 1/669)
Other rulings and issues related to this hadith will be mentioned under Kitab al-Jihad, Hadith 3049,
by the permission of Allah Ta‘ala.
