Jami` at-Tirmidhi Book 48, Hadith 171
“Allah, Blessed is He and Most High, said: ‘O son of Adam! Verily as long as you called upon Me and hoped in Me, I forgave you, despite whatever may have occurred from you, and I did not mind. O son of Adam! Were your sins to reach the clouds of the sky, then you sought forgiveness from Me, I would forgive you, and I would not mind. So son of Adam! If you came to me with sins nearly as great as the earth, and then you met Me not associating anything with Me, I would come to you with forgiveness nearly as great as it.’”
when death reached him, he said: “I have concealed something I heard from the Messenger of Allah (ﷺ) from you. I heard the Messenger of Allah (ﷺ) saying: ‘If you did not sin, Allah would create a creation that would sin, so He will forgive them.’”
“Allah created a hundred mercies, and He placed one mercy among his creation, they show mercy to one another by it, and there are ninety-nine mercies with Allah.”
