Musnad Ahmad Hadith 26694

It is narrated from Umm Salamah (may Allah be pleased with her) that once Abdur Rahman bin Auf came to her and said, "Mother, I fear that the abundance of wealth may destroy me, because I am the wealthiest among the Quraysh." She replied, "Son, spend it, because I heard the Prophet (ﷺ) say that some of my companions will be such that after my separation from them, they will never see me again." When Abdur Rahman bin Auf went out, he met Umar on the way and told him this. Umar himself went to Umm Salamah and, entering the house, said, "Swear by Allah and tell me, am I also among them?" She replied, "No, but after you, I cannot say this about anyone."
