Jami` at-Tirmidhi 3548
جامع الترمذي#3548Da'ifIbn `Umar narrated that the Messenger of Allah (ﷺ) said:“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.”
