The Messenger of Allah (ﷺ) said that Allah the Exalted said:
"'Oh son of Adam, if you call upon me and place your hope in me, I will forgive you without any reservation.
Oh son of Adam, if you have sins piling up to the clouds and then ask for my forgiveness, I will forgive you without any reservation.
Oh son of Adam, if you come to me with enough sins to fill the earth and you meet me without associating a partner with me, I will come to you with enough forgiveness to fill the earth.'"
[40 Hadith Nawawi #42] [Sunan At-Tirmidhi 3540]
