The Prophet (ﷺ) said, "When a faithful believer is made to sit in his grave, then (the angels) come to him and he testifies that La ilâha ill- Allah wa anna Muḥammad-ar-Rasûl Allah (none has the right to be worshipped but Allâh and Muhammad (ﷺ) is Allâh's Messenger (ﷺ))." And that corresponds to Allâh's Statement: " Allâh will keep firm those who believe with the word that stands firm...." (V.14:27). [2:450-O.B.]
