It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: The Prophet (peace and blessings be upon him) said to me: "O Aishah! The quickest of people to perish will be the people of your tribe." I said: "May Allah make me your ransom! Is it (Banu) Taym?" He (peace and blessings be upon him) said: "No, rather this tribe of Quraysh; deaths will snatch them away, and people will envy them (for their standing)." I said: "Then how will people survive after them?" He (peace and blessings be upon him) said: "They are the backbone of the people; so when they perish, (all the rest of the) people will perish."
No one narrated this hadith from Ibn Abi Mulaykah (may Allah have mercy on him) except Abdullah bin al-Mu'ammal (may Allah have mercy on him).
