Mukhtasar Bukhari

Narrated by Sayyiduna Bara’ bin Azib from the Noble Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: “When a believer is made to sit up in his grave and his angels come to him, then he bears witness that there is no deity except Allah and that Muhammad (peace and blessings be upon him) is the Messenger of Allah. Thus, what Allah the Exalted has said (in Surah Ibrahim, verse 27): ‘Allah keeps firm those who believe, with the firm word, in the life of this world and in the Hereafter,’ this is what it means.”
