Musannaf Ibn Abi Shaybah 36950 — The words of Isa (peace be upon him)

Khaythamah said: Isa bin Maryam (peace be upon him) said: "Blessed are the children of the believer; blessed are they, for even after he (the believer) has died they are protected (because of him)." Having said this, Khaythamah recited this verse: "And their father was a righteous man" [Al-Kahf: 82] (which is why their treasure was protected).
