It was
narrated that ‘Aishah said:
“The Prophet (ﷺ) used to spend
the
night in a state of sexual impurity, then Bilal would come to him
and
inform him that it is time for prayer. So he would get up and have
a
bath, and I would see the water dripping from his head, then he
would
go out and I would hear his voice during Fajr prayer.” (One of the narrators) Mutarrif said: "I said to Amir: 'Was that during Ramadan?' He said: 'In
Ramadan and at other times.'"
