It is narrated from Sayyidah Umm Hani bint Abi Talib (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Allah Almighty has favoured Quraysh with seven qualities: (1) that I am from among them; (2) that prophethood is among them; (3) the custodianship of the Ka'bah (hijabah) is among them; (4) giving water to the pilgrims (siqayah) is among them; (5) that Allah helped them against the people of the Elephant; (6) that they worshipped Allah for ten years (in such a way) that no one besides them worshipped Him; (7) and that Allah Almighty revealed a surah of the Qur'an about them." Then the Messenger of Allah (peace and blessings be upon him) recited it: "In the name of Allah, the Most Gracious, the Most Merciful. For the accustomed security of Quraysh, their accustomed security in the caravan of winter and summer, let them worship the Lord of this House, who fed them against hunger and made them safe from fear" [Surah Quraysh: 1-4] . The chain of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.
