{" Verily, there has come to you a Messenger from amongst yourselves. It grieves him that you should experience any injury or difficulty. He is anxious over you; for the believers, he is full of pity, kind, and merciful."} [at-Tawbah; 128]
'A'ishah narrated:
"Once, when I saw the Prophet in a good mood, I said to him: "O Messenger of Allah! Supplicate to Allah for me!"
So, he said: "O Allah! Forgive 'A'ishah her past and future sins, what she has hidden, as well as what she has made apparent."
So, I began smiling, to the point that my head fell into my lap out of joy.
The Messenger of Allah said to me: "Does my supplication make you happy?"
I replied: "And how can your supplication not make me happy?"
He then said: "By Allah, it is the supplication that I make for my Ummah in every prayer.""
