It was narrated that Anas said: “The Messenger of Allah (peace be upon him) said: ‘Do not pray for death or wish for it. Whoever insists on praying for it let him say: Allahumma ahini ma kanatil-hayatu khairanli wa tawaffani idha kanatil-wafatu khairanli (O Allah, keep me alive so long as life is good for me, and cause me to die when death is good for me.)”‘
Sunan an-Nasa’I, Book 21, Hadith 5
