Musnad Abu Ya'la al-Mawsili 147:68

Yahya ibn Ayyub narrated to us, Yahya ibn Sulaym narrated to us, he said: Two men from the people of Harran, from the people of knowledge, and they were trustworthy to me, narrated to me, from Zufar ibn Muhammad, from Muhammad ibn Abdullah ibn Amr ibn Uthman ibn Affan, from Anas ibn Malik, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no person who lives in Islam for forty years except that Allah repels from him types of afflictions: madness, leprosy, and vitiligo. When he reaches fifty, Allah makes the reckoning easy for him. When he reaches sixty, Allah grants him the provision of turning in repentance to Allah in a way that Allah loves. When he reaches seventy, Allah loves him and the inhabitants of the heavens love him. When he reaches eighty, his good deeds are recorded and his evil deeds are erased. When he reaches ninety, Allah forgives him his past and future sins, he becomes the prisoner of Allah on His earth, and he is granted the right of intercession for the people of his household."
