"(And for such of your women as despair of menstruation…) [65:4]. Said Muqatil: “When the verse (Women who are divorced shall wait, keeping themselves apart…), Kallad ibn al-Nu‘man ibn Qays al-Ansari said: ‘O Messenger of Allah, what is the waiting period of the woman who does not menstruate and the woman who has not menstruated yet? And what is the waiting period of the pregnant woman?’ And so Allah, exalted is He, revealed this verse”. Abu Ishaq al-Muqri’ informed us> Muhammad ibn ‘Abd Allah ibn Hamdun> Makki ibn ‘Abdan> Abu’l-Azhar> Asbat ibn Muhammad> Mutarrif> Abu ‘Uthman ‘Amr ibn Salim who said: “When the waiting period for divorced and widowed women was mentioned in Surah al-Baqarah, Ubayy ibn Ka‘b said: ‘O Messenger of Allah, some women of Medina are saying: there are other women who have not been mentioned!’ He asked him: ‘And who are they?’ He said: Those who are too young [such that they have not started menstruating yet], those who are too old [whose menstruation has stopped] and those who are pregnant’. And so this verse (And for such of your women as despair of menstruation…) was revealed”."
