Sayyidah Aishah (may Allah be pleased with her) said: During his final illness, the Messenger of Allah (peace and blessings be upon him) sent for his wives. When they had all gathered, he (peace and blessings be upon him) said: "I no longer have the strength to go round to all of you. If you would permit me to stay with Aishah." So they permitted him.
Imam al-Shafi'i (may Allah have mercy on him) said: When he (peace and blessings be upon him) was asked: Who among the people is most beloved to you (peace and blessings be upon him)? He said: "Aishah."
