Narrated 'Aishah: We were seated in our house in the noonday heat. Someone said to Abu Bakr: Here is the Messenger of Allah (ﷺ) coming to us shading his head at the hour when he would not generally come. The Messenger of Allah (ﷺ) then came; he asked for permission and he gave him permission and he entered.
