Silsilat al-Ahadith al-Sahihah

Lady Umm Salamah (may Allah be pleased with her) says that Abdur Rahman bin Awf (may Allah be pleased with him) came to me and said: “Mother! I am the richest man among the Quraysh, and I am afraid that this abundance of wealth may destroy me.” She said: “My son! Spend (in charity), because I heard the Messenger of Allah (peace and blessings be upon him) say: ‘Some of my companions are such that after my separation, they will not meet me.’” He left from there and met Sayyiduna Umar (may Allah be pleased with him), (and narrated this hadith to him). Sayyiduna Umar came to Lady Umm Salamah and said: “By Allah! Am I also among them?” She said: “No. But after you, I will not inform anyone.”
