The Prophet ﷺ said, "Ayesha, the first people to perish will be your own people."Ayesha said, "May Allah make me your ransom. Do you mean my tribe of Taym?"He replied, "No, but this clan of Quraysh. Death will overtake them, and others will be relieved of them. They will be the first of mankind to perish."She asked, "And what will become of the people after them?"He said, "They are the backbone of the people. When they perish, the people will perish."
حدثنا موسى بن داود قال حدثنا عبد الله بن المؤمل عن ابن أبي مليكة
