O Allaah, forgive me, have mercy upon me and unite me with the highest companions
'Aa.ishah (radhi-yAllaahu 'anhaa) related that The Prophet (sal-Allaahu 'alayhe wa sallam) [during his illness in which he passed away] would dip his hands in water and then he would wipe his face and say: ‘None has the right to be worshipped except Allaah, death does indeed contain agony.’
(None has the right to be worshipped except Allah and Allah is the greatest.None has the right to be worshipped except Allah, alone.None has the right to be worshipped except Allah, alone, without partner.None has the right to be worshipped except Allah, to Him belongs all sovereignty and praise. None has the right to be worshipped except Allah and there is no might and no power except with Allah.)
