Among the examples of the first subdivision are: Muḥammad b. Sinān—with the sīn (1) vocalised with a kasra and two nūns with an alif between them. A number of narrators bear this name; among them is al-ʿAwaqī—with a fatḥa on the ʿayn and the wāw and then a qāf (2)—one of al-Bukhārī’s (3) teachers.
Another instance is Muḥammad b. Sayyār—whose initial undotted consonant carries a fatḥa, the yāʾ below is doubled with a shadda, and a rāʾ follows the alif—of whom there are likewise several individuals (4). Among them is al-Yamāmī (5), the teacher of ʿUmar b. Yūnus.
Also included (6) are Muḥammad (7) b. Ḥunayn—spelled with the undotted consonant bearing a ḍamma (8), two nūns (9) the first of which is fatḥa-marked, and a yāʾ between them—a tābiʿī who narrated from Ibn ʿAbbās and others; and Muḥammad b. Jubayr—beginning with a jīm (10), followed by a one-dotted letter (11), and ending with a rāʾ—namely Muḥammad b. Jubayr b. Muṭʿim (12), a well-known tābiʿī as well.
Another illustration is Muʿarrif b. Wāṣil, a famous Kufan, and Muṭarrif (13) b. Wāṣil—with a ṭāʾ replacing the ʿayn—another shaykh from whom Abū Ḥudhayfa al-Nahdī transmitted.
