Sahih Muslim

Umm Salama reported Allah's Messenger (ﷺ) as saying:Whenever you visit the sick or the dead, supplicate for good because angels say"" Amen"" to whatever you say. She added: When Abu Salama died, I went to the Messenger of Allah (ﷺ) and said: Messenger of Allah, Abu Salama has died. He told me to recite:"" O Allah! forgive me and him (Abu Salama) and give me a better substitute than he."" So I said (this), and Allah gave me in exchange Muhammad, who is better for me than him (Abu Salama)
