The Messenger of Allah (ﷺ) as saying: If anyone's last words are "There is no god but Allah" he will enter Paradise.
Sunan Abi Dawud Book 21, Hadith 28
← Previous Hadith The Messenger of Allah (ﷺ): When you attend dying man, you should say good words, for the angels say Amin to what you say. When Abu Salamah died, I said: What should I say, Messenger of Allah? He said: O Allah forgive him, and give us something good in exchange. She said: So Allah gave me Muhammad (ﷺ) in exchange for him.
