’Aa‘ishah (radiyallaahu ’anhaa) reported that:
A Jewess came to her and mentioned the Punishment of the Grave, saying to her: May Allaah protect you from the Punishment of the Grave. So she asked the Messenger of Allaah (sallallaahu ’alayhi wa sallam) about it and he said, “Yes, there is Punishment in the Grave!” ’Aa‘ishah (radiyallaahu ’anhaa) said: After that, I never saw the Messenger of Allaah (sallallaahu ’alayhi wa sallam), except that he sought refuge from the Punishment of the Grave in every Prayer that he prayed.
