Riyad as-Salihin

`Aishah (May Allah be pleased with her) reported: While the Prophet (ﷺ) was reclining against me (during his last illness) I heard him saying: "Allahumma-ghfir li, warhamni, wa alhiqni bir Rafiqil-A`la (O Allah, forgive me, bestow Your Mercy on me and let me join with the exalted companions.''
