Al蘋 ibn Ab蘋 廜珀??ib (Arabic: 媢?? 堥? 堧嚘輔 媟塈?堥) was the cousin and son-in-law of the Islamic prophet Muhammad, ruled over the Islamic Caliphate from 656 to 661, and was the first male convert to Islam.

Sunni Muslims consider Ali the fourth and final of the Rashidun (rightly guided Caliphs), while Shi'a Muslims regard Ali as the first Imam and consider him and his descendants the rightful successors to Muhammad, all of whom are members of the Ahl al-Bayt, the household of Muhammad.

This disagreement divides the Ummah (Muslim community) into the Sunni and Shi'a branches. Ali is greatly revered in Shia Islam. Zulfiqar 'bifurcated' (Arabic: 堸? 塈???塈堭??Dh贖 l-Fiq?r) is the sword of Ali. In Arabic the name is commonly transliterated as Dhu al-Fiqar, Thulfeqar, Dhulfiqar, Zoulfikar etc.

Representations of the Prophet Muhammad are controversial, and generally forbidden in Sunni Islam (especially Hanafiyya, Wahabi, Salafiyya). Shia Islam and some other branches of Sunni Islam (Hanbali, Maliki, Shafi'i) are generally more tolerant of such representational images, but even so the Prophet's features are generally veiled or concealed by flames as a mark of deep respect.
