VII Commencement of War with the Tribes of Najd and the Jews, the Marriage of Ḥaḍrat Fāṭimah and Ḥafṣah, and a Few Miscellaneous Incidents Ghazwah Qarqaratul-Kudr - Shawwāl 2 A. H. It has already been mentioned that after the migration, the Quraish of Makkah toured the various tribes of Arabia and turned many of them into deadly enemies of the Muslims. Among these tribes, with respect to strength and number, the most noteworthy were two tribes residing in the central region of Arabia, known as Najd. Their names were Banū Sulaim and Banū Ghaṭafān. The Quraish of Makkah had especially tied these two tribes to themselves and incited them against the Muslims. As such, Sir William Muir writes: “The Coreish now turned their eyes towards this territory [i. e. , Najd], and entered into closer bonds with the tribes inhabiting it. Henceforth the attitude of the Bani Suleim and Ghatafân, especially of the former, became actively hostile towards Mahomet. Incited by the Coreish, and by the example of Abū Sofiân, they now projected a plundering attack upon Medîna. ” 1 1 The Life of Mahomet, By Sir William Muir, Chapter XIII, Expeditions Against Hostile Tribes in Nejd, p. 253, Published by Smith, Elder, & Co.
