ALLAH'S FORGIVENESS KNOWS NO BOUNDS
Anas رَضِيَ اللهُ عَنْهُ narrated that Allah's Messenger ﷺ said that Allah, the exalted, says, "O son of Aadam, as long as you pray to me and place hope in Me, I will forgive you in spite of what is against you. I do not mind! O son of Aadam, if your sin reach the borders of the sky and you seek My forgiveness, I shall forgive you. I do not mind. O son of Aadam, were you to come to me with sins as many as would fill the earth and you meet me without having associated any thing with me, I shall come to you with as much forgiveness as would fill the earth."
Abu Dharr رَضِيَ اللهُ عَنْهُ , narrated that it too.
