In one narration the words are: "When he becomes 60 years old, Allah Almighty grants him turning to Allah in the way He loves. When he becomes seventy years old, Allah Almighty forgives his past and future sins, he is the captive of Allah on Allah's earth, and his intercession for the members of his household will be accepted." Abu Ya'la recorded all these narrations with various chains.
