forgiveness

Hadith Qudsi 34

On the authority of Anas (may Allah be pleased with him), who said: I heard the Messenger of Allah (peace be upon him) say: Allah the Almighty said: O 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.

And consult with them in ways that are best and most gracious."[16:125]
