Abu Musa Al-Ash'ari (May Allah be pleased with him) reported:
Messenger of Allah (ﷺ) said, "On the Day of Resurrection, Allah will deliver to every Muslim, a Jew or a Christian and say: 'This is your ransom from Hell-fire."'Another narration is: Messenger of Allah (ﷺ) said, "There would come people amongst the Muslims on the Day of Resurrection with sins as heavy as a mountain, and Allah would forgive them".[Muslim].
