Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings of Allah be upon him) said during his illness of death: "Fear Allah regarding the prayer and your slaves (and your wealth)." The Prophet (peace and blessings of Allah be upon him) repeated these words again and again.
