Narrated Aisha (RA), she said, ‘The Prophet (ﷺ) was leaning towards me. Then I heard him say -

اَللَّهُمَّ اغْفِرْ لِي، وَارْحَمْنِي، وَأَلْحِقْنِي بِالرَّفِيقِ الْأَعْلَى

Allahum-maghfir lee warhamnee wa 'alhiqnee bir-rafeeqil-'a'laa

O Allah, forgive me and have mercy upon me and join me with the highest companions (in Paradise).
