Sign of the Day of Judgment: The end of Quraish will occur
وعن أبى هريرة رضى الله عنه قال قال رسول الله صلى الله عليه وسلم: أسرع قبائل العرب فناء قريش ويوشك أن تمر المرأة بالنعل فتقول: إن هذا نعل قرشي
It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: "Among the Arab tribes, the Quraysh will be the first to perish, and it is possible that a woman will pass by carrying a shoe and say, 'This is the shoe of so-and-so from Quraysh.'"
Reference: Ahmad (444/2) Musnad al-Bazzar (298/3) Abu Ya'la (68/11) Al-Tarikh al-Kabir (221/4) Al-Silsilah al-Sahihah (364/2)
It is narrated from Hazrat Aisha (may Allah be pleased with her) that the Messenger of Allah (peace be upon him) said: "O Aisha! Your people will be the first to be destroyed." Hazrat Aisha (may Allah be pleased with her) said: "O Messenger of Allah! May Allah sacrifice me for you, will the Banu Tamim be the first to perish?" He said: "No! Rather, this tribe of Quraysh will be the first to face death and their destruction will be before all others." Hazrat Aisha (may Allah be pleased with her) asked: "Then who will remain?" He said: "The same (Quraysh) who were the center of the people; when they perish, then (without delay) all people will perish."
Reference: Ahmad (28/6 - 95 - 105) Al-Silsilah al-Sahihah (596/4)
Benefits:
(1) The destruction of Quraysh is a sign of the Day of Judgment and a prophecy of the Prophet Muhammad (peace be upon him) which will inevitably come true.
(2) This prophecy and sign have not yet been fully fulfilled, but the majority of Quraysh have become extinct today and very few Qurayshis remain.
(3) Quraysh is superior to all other tribes.
(4) The virtue of Quraysh is established, but it is not correct to elevate them to the rank of prophets or to raise them above the prophets. Especially in our region, particularly Sindh, it is customary for ignorant people to start kissing the feet of any Qurayshi (Sayyid) as soon as they hear of him.
(5) Many impostors are falsely claiming to be Qurayshi in order to attain the aforementioned high status.
