The Ḥums were the Quraysh, Banu Kinanah, Banu Khuza'a and Banu 'Amir. They did not perform the pilgrimage outside the zone of Mecca's haram, thus excluding Mount Arafat. They also developed certain dietary and cultural restrictions. According to Kitab al-Muhabbar, the Ḥilla denoted most of the Banu Tamim, Qays, Rabi`ah, Qūḍa'ah, Ansar, Khath'am, Bajīlah, Banu Bakr ibn Abd Manat, Hudhayl, Asad, Tayy and Bariq. The Ṭuls comprised the tribes of Yemen and Hadramaut, 'Akk, Ujayb and Īyād. The Basl recognised at least eight months of the calendar as holy. There was also another group which didn't recognize the sanctity of Mecca's haram or holy months, unlike the other four.
