Ibn 'Umar said, "I heard the Prophet, may Allah bless him and grant
him peace, asking Allah to forgive him a hundred times in this assembly
with the words, 'O Allah, forgive me and turn to me and show mercy to me.
You are the Ever-Turning back (to his slaves), Merciful.'"
'Abdullah ibn 'Amr reported that a man said, "O Allah, forgive
me and Muhammad alone!" The Prophet, may Allah bless him and grant him
peace, said, "You have veiled it from many people."
Safwan ibn 'Abdullah ibn Safwan, who was married to the daughter
of Abu'd-Darda', said, "I visited them in Syria and found Umm ad-Darda'
in the house, but not Abu'd-Darda'. She asked, 'Are you intending to go
on hajj this year?' 'Yes,' I replied. She said, 'Make supplication to Allah
and ask for good for us. The Prophet, may Allah bless him and grant him
peace, said, "The supplication of a Muslim man for his absent brother is
answered. At his head there is a guardian angel. Whenever he asks Allah
to give his brother good, the angel says, 'Amen, and may you have the same.'"'
I met Abu'd-Darda' in the market and he said something similar which was
related from the Prophet, may Allah bless him and grant him peace."
