‘Amr ibn Al-‘Aas narrates, “When Islam entered my heart, I went to the Messenger of Allah and said, ‘Give me your hand so that I may pledge allegiance to you.’ The Prophet (SAW) spread his hand, but I withdrew mine. He said, ‘What is wrong ‘Amr?’ I said, ‘I want to make a condition.’ ‘And what is that?’ he said. I said, ‘That Allah will forgive me.’ Then the Messenger of Allah said, ‘Did you not know that Islam wipes out what came before it, and that Hijrah wipes out what came before it and that Hajj wipes out what came before it!” – Sahih Muslim
