Aisha (Allah be pleased with her) reported that there came Aflah the brother, of Abul Quais, who sought her permission (to enter) after seclusion was instituted, and Abu Quais was the father of Aisha by reason of fosterage. Aisha said: By Allah, I would not permit Aflah unless I have solicited the opinion of Allahs Messenger ﷺ for Abu Quais has not suckled me, but his wife has given me suck. Aisha (Allah be pleased with her) said: When Allahs Messenger ﷺ entered, I said: Allahs Messenger, Aflah is the brother of Abul-Quais; he came to me to seek my permission for entering (the house). I did not like the idea of granting him permission until I had solicited your opinion. Thereupon Allahs Apostle ﷺ said: Grant him permission. Urwa said it was on account of this that Aisha used to say: What is unlawful by reason of consanguinity is unlawful by reason of fosterage.
