(Allah chargeth you concerning (the provision for) your children…) [4:11].
Ahmad ibn Muhammad ibn Ahmad ibn Ja'far informed us> al-Hasan ibn Ahmad al-Makhladi> al-Mu'ammil ibn al-Hasan ibn 'Isa> al-Hasan ibn Muhammad ibn al-Sabbah> Hajjaj> Ibn Jurayj> Ibn al-Munkadir> Jabir who said: “The Messenger of Allah, Allah bless him and give him peace, and Abu Bakr came on foot to visit me at Banu Salamah when I was sick. He found me unconscious. He asked for some water, performed minor ritual ablution and then sprinkled some of the water on me and I woke up. I said: 'O Messenger of Allah! What shall I do with my wealth?' And so the verse (Allah chargeth you concerning (the provision for) your children: to the male the equivalent of the portion of two females…)”. This was narrated by Bukhari> Ibrahim ibn Musa> Hisham, and also by Muslim> Muhammad ibn Hatim> Hajjaj; and both Hisham and Hajjaj related this tradition from Ibn Jurayj.
Abu Mansur Muhammad ibn Muhammad al-Mansuri informed us> 'Ali ibn 'Umar ibn Mahdi> Yahya ibn Sa'id>> Ahmad ibn al-Miqdam> Bishr ibn al-Mufaddal> 'Abd Allah ibn Muhammad ibn 'Aqil> Jabir ibn 'Abd Allah who said: “A woman came to the Messenger of Allah, Allah bless him and give him peace, with her two daughters and said: 'O Messenger of Allah! These are the daughters of Thabit ibn Qays, or perhaps she said Sa'd ibn al-Rabi', who was killed fighting on your side at the Battle of Uhud. Their uncle has taken possession of their fortune and inheritance and did not leave anything belonging to them except that he took it to himself, so what do you think, O Messenger of Allah? For by Allah, they will never get married unless they have some money'. The Messenger of Allah said to her: 'Allah will judge for you concerning this'. And so Surah al-Nisa' was revealed which contains (Allah chargeth you concerning (the provision for) your children: to the male the equivalent of the portion of two females…). The Messenger of Allah, Allah bless him and give him peace, then said to me: 'Summon for me the woman and her adversary'. He said to the uncle of the girls: 'Give the girls two third of the fortune, their mother one eighth and keep the remainder' ”.
