Whoever supplicates for his brother (in Islam) in his absence, an angel is appointed to his side who says “Ameen (so be it) and may you also be blessed with the same.”
O Allah! You are forgiving, and you love forgiveness. So forgive me.
For a wound to heal, you have to clean it out. Again, and again, and again. And this cleaning process stings. The cleaning of a wound hurts. Yes. Healing takes so much work. So much persistence. And so much patience. But every process has an end and an appointed term. Your healing will come, God willing. And like all created things, your worldly pain will die.
Hadith Qudsi 34:
On the authority of Anas (may Allah be pleased with him), who said: I heard the Messenger of Allah (PBUH) say: Allah the Almighty said:
"Oh son of Adam, so long as you call upon Me and ask of Me, I shall forgive you for what you have done, and I shall not mind. O son of Adam, were your sins to reach the clouds of the sky and were you then to ask forgiveness of Me, I would forgive you. O son of Adam, were you to come to Me with sins nearly as great as the earth and were you then to face Me, ascribing no partner to Me, I would bring you forgiveness nearly as great at it."
[It was related by at-Tirmidhi (also by Ahmad ibn Hanbal). Its chain of authorities is sound]
