Narrated `Aisha: I heard the Prophet, who was resting against me, saying, "O Allah! Excuse me and bestow Your Mercy on me and let me join with the highest companions (in Paradise)." See Qur'an (4.69)
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ عَبَّادِ بْنِ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، قَالَ سَمِعْتُ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم وَهْوَ مُسْتَنِدٌ إِلَىَّ يَقُولُ " اللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَأَلْحِقْنِي بِالرَّفِيقِ الأَعْلَى " .
