Abu Bakr's recitation
during the prayer could
not be heard due to his weeping:
“During his illness the Messenger of Allâh (saw) said: “Order Abű
Bakr
to lead the prayer”. ‘Aisha said, “I told the Messenger of Allâh (saw) that indeed, if Abű Bakr
stands in your place (to lead the people in prayer) the people will not be able to
hear him due to his (excessive) weeping. So order ‘Umar to lead the prayer.” The Prophet (saw) said again: “Order
Abű Bakr to lead the prayer”. Then ‘Aisha told Hafsah: “Tell the Messenger of
Allâh (saw) that if Abű Bakr stands in your place, the people will not be able to
hear him
due to his weeping, so order ‘Umar to lead the people in prayer”. So Hafsah did this and
the Prophet (saw) replied: “Desist! Verily you are like the companions of Yűsuf[2].
Order Abű Bakr to lead the prayer.”"
