Musnad Ahmad 32:1336

Anas ibn Iyad narrated to us, Yusuf ibn Abi Dhurrah al-Ansari narrated to me, from Ja'far ibn 'Amr ibn Umayyah al-Damri, from Anas ibn Malik, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no person who lives to the age of forty years in Islam, except that Allah diverts from him three types of affliction: insanity, leprosy, and vitiligo. When he reaches fifty years, Allah makes his reckoning easy for him. When he reaches sixty, Allah grants him the provision of turning to Him in a manner that He loves. When he reaches seventy years, Allah loves him, and the inhabitants of the heavens love him. When he reaches eighty, Allah accepts his good deeds and overlooks his evil deeds. When he reaches ninety, Allah forgives him his past and future sins, he is named the prisoner of Allah on His earth, and he is granted the right of intercession for his household."
