It was narrated from Al Bara’ bin ‘Azib that the Prophet صلی اللہ علیہ وآلہ وسلم said: “Allah will keep firm those who believe, with the word that stands firm in this world, and in the Hereafterj This was revealed concerning the torment in the grave. It will be said to him (the deceased): ‘Who is your Lord?’ And he will say: ‘My Lord is Allah and my Prophet صلی اللہ علیہ وآلہ وسلم is Muhammad ‘ That is what is (the meaning of) His saying: Allah will keep firm those who believe, with the word that stands firm in this world, and in the Hereafter.” (Sahih)
