"By Allah, it is the supplication that I make for my Ummah in every prayer."

{" 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."}

[Qur'an at-Tawbah 9; 128]

SubhanAllah, a beautiful, beautiful hadith, may Allah Bless the Prophet (saw) with the best of Blessings (Ameen):

'A'ishah (RA) 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.""
