وَعَنْ أُمِّ سَلَمَةَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ كَانَ يَقُولُ فِي مَرَضِهِ: «الصَّلَاةَ وَمَا مَلَكَتْ أَيْمَانُكُمْ» . رَوَاهُ الْبَيْهَقِيُّ فِي شعب الْإِيمَان وَرَوَى أَحْمَدُ وَأَبُو دَاوُدَ عَنْ عَلِيٍّ نَحْوَهُ

Umm Salama told that the Prophet was saying during his illness, “Maintain the prayer and care for your slaves.” Baihaqi transmitted it in Shu'ab al-iman, and Ahmad and Abu Dawud transmitted something similar on the authority of ‘Ali.
