I heard the Prophet ﷺ , 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)

سَمِعْتُ النَّبِيَّ ﷺ وَهْوَ مُسْتَنِدٌ إِلَىَّ يَقُولُ اللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَأَلْحِقْنِي بِالرَّفِيقِ الأَعْلَى

O Allah, grant me pardon, show mercy to me, enjoin me to companions (on High).

أَنَّهَا سَمِعَتْ رَسُولَ اللَّهِ ﷺ يَقُولُ قَبْلَ أَنْ يَمُوتَ وَهُوَ مُسْنِدٌ إِلَى صَدْرِهَا وَأَصْغَتْ إِلَيْهِ وَهُوَ يَقُولُ اللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَأَلْحِقْنِي بِالرَّفِيقِ

Yahya related to me from Malik from Hisham ibn Urwa from Abbad ibn Abdullah ibn az-Zubayr that A'isha, the wife of the Prophet ﷺ told him that she had heard the Messenger of Allah ﷺ say before he died, while he was leaning on her breast and she was listening to him, "O Allah, forgive me and have mercy on me and join me with the highest company."

أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ أَخْبَرَتْهُ أَنَّهَا سَمِعَتْ رَسُولَ اللَّهِ ﷺ قَبْلَ أَنْ يَمُوتَ وَهُوَ مُسْتَنِدٌ إِلَى صَدْرِهَا وَأَصْغَتْ إِلَيْهِ يَقُولُ اللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَأَلْحِقْنِي بِالرَّفِيقِ الأَعْلَى

O Allah, grant me pardon, show mercy to me, enjoin me to companions (on High). (Using translation from Muslim 2444a)

أَنَّهَا سَمِعَتِ النَّبِيَّ ﷺ وَأَصْغَتْ إِلَيْهِ قَبْلَ أَنْ يَمُوتَ وَهِيَ مُسْنِدَتُهُ إِلَى صَدْرِهَا يَقُولُ «اللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَأَلْحِقْنِي بِالرَّفِيقِ الْأَعْلَى»

"سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ وَهُو مُسْتَنِدٌ إِلَى صَدْرِي: اللَّهُمَّ اغْفِر لِي وارحمني، وَأَلْحِقْنِي بِالرَّفِيقِ الأَعْلَى".
