English Translation
Narrated to us by Bahz, who said: Hammam narrated to us: Qatadah narrated to us, from Abu al-Khalil, from Safinah, the mawla of Umm Salamah, from Umm Salamah, that the Prophet (peace and blessings be upon him), when death came to him, kept saying: "The prayer, the prayer, and those whom your right hands possess" - repeating it, though his tongue could hardly manage it.
