"Let a man of wealth spend according to his wealth, and he whose provision is restricted, let him spend from what Allah has given him"

Imam al-Shafi'i (may Allah be pleased with him) said regarding the maintenance owed by a (husband) of limited means: "It is one mudd per day, by the mudd of the Prophet (peace and blessings be upon him), from the (common) food of the town."
He said: "I set this obligatory amount at one mudd on the basis of the evidence from the Messenger of Allah (peace and blessings be upon him) regarding the man who had intercourse with his wife during the month of Ramadan: he (peace and blessings be upon him) gave him a basket containing fifteen sa' for (feeding) sixty poor people, which comes to one mudd for each poor person. The basket was of fifteen sa'; it used to be made to that measure so that four baskets would make one wasq. However, the one who narrated the hadith to them introduced a doubt into it: whether it was fifteen sa' or twenty sa'."

It is reported from Sa'id bin al-Musayyib (may Allah have mercy on him), concerning the story of the Bedouin who had intercourse with his wife in Ramadan, that he said: A basket of dates was brought to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Take this and give it in charity." And he mentioned it (i.e. the long hadith). Ata' (may Allah have mercy on him) said: I asked Sa'id (may Allah have mercy on him) how many dates were in that basket. He said: Between fifteen and twenty sa'.

Abu Hurayrah (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him), concerning the story of the man who had intercourse (with his wife in Ramadan), that he (peace and blessings be upon him) said: "Feed sixty poor people." He said: I do not have (the means). Then a basket was brought to the Messenger of Allah (peace and blessings be upon him) containing fifteen sa' (of dates). He said: "Take it and give it in charity." Abu Amr al-Adib informed us of it; Abu Bakr al-Isma'ili informed him from Ahmad bin Muhammad bin Mansur al-Katib, who said: Al-Hakam bin Musa narrated to us; Hiql narrated to us from al-Awza'i, who said: Al-Zuhri narrated to me, and he mentioned it.
This is how it was narrated from al-Awza'i, with (the measure) interpolated (mudraj) into al-Zuhri's hadith from Humayd. Ibn al-Mubarak (may Allah have mercy on him) narrated it from al-Awza'i and placed the estimate of the basket in the narration of Amr bin Shu'ayb (may Allah have mercy on him), and we have mentioned it in another place.
Imam al-Shafi'i (may Allah have mercy on him) said: The maintenance owed by one who is well-off is two mudds. I set the most that I imposed at two mudds each because the most that the Prophet (peace and blessings be upon him) set in the ransom of expiation for (head) ailment was two mudds for each poor person.

It is narrated from Ka'b bin Ujrah (may Allah be pleased with him) that he was with the Prophet (peace and blessings be upon him) in the state of ihram, and lice troubled him. The Messenger of Allah (peace and blessings be upon him) ordered him to shave his head and said: "Fast three days, or feed six poor people two mudds each, or sacrifice a goat; whichever of these you do will suffice for you." Al-Husayn bin al-Walid narrated it from Malik with a good chain, and the two Shaykhs (may Allah have mercy on them) recorded it in their Sahih through other chains from Abd al-Karim.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he fixed twelve dirhams for a woman and her servant: eight dirhams for the woman and four dirhams for the servant, and of the eight, one dirham was for cotton and linen. Its chains are weak.
