(27) باب فِي الْمَسْأَلَةِ فِي الْقَبْرِ وَعَذَابِ الْقَبْرِ
Al-Bara' b. 'Azib reported the Messenger of Allah(ﷺ) as saying:
When a Muslim is questioned in the grave he testifies that there is no god but Allah and that Muhammad is Allah's Apostle. That is verified by Allah's words: "Allah establishes those who believe with the word that stands firm."
