Jami` at-Tirmidhi Book 48, Hadith 180
“Ishaq bin Mansur narrated to us, from Isra’il” with this (Another chain) Bilal narrated that the Messenger of Allah (ﷺ) said: “Hold fast to Qiyam al-Lail, for it is the practice of the righteous before you, and indeed Qiyam al-Lail is a means of nearness to Allah, a means of prevention from sin, an expiation for bad deeds, and a barrier for the body against disease.”
“Whomsoever of you the door of supplication is opened for, the doors of mercy have been opened for him. And Allah is not asked for anything - meaning - more beloved to Him, than being asked for Al-`Āfiyah.” And the Messenger of Allah (ﷺ) said: “The supplication benefits against that which strikes and that which does not strike, so hold fast, O worshippers of Allah, to supplication.”
The Messenger of Allah (ﷺ) said: “The lifespan of my nation is between sixty to seventy, and the least of them are those who surpass that.”
