Volume 1, Book 6, Number 322:
Narrated ‘Aisha:
Fatima bint Abi Hubaish asked the Prophet, “I got persistent bleeding (in between the periods) and
do not become clean. Shall I give up prayers?” He replied, “No, this is from a blood vessel. Give up the
prayers only for the days on which you usually get the menses and then take a bath and offer your
prayers.”
