The official religion of Pakistan is Islam, as enshrined by Article 2 of the Constitution, and is practised by an overwhelming majority of 96.35% of the country's population. The remaining 3.65% practice Hinduism, Christianity, Ahmadiyya (considered a non-Muslim group as per the Pakistani constitution), Sikhism, Zoroastrianism and other religions.
Muslims comprise a number of sects: the majority practice Sunni Islam (estimated at 85-90%), while a minority practice Shia Islam (estimated at 10-15%). Most Pakistani Sunni Muslims belong to the Hanafi school of jurisprudence, which is represented by the Barelvi and Deobandi traditions. However, the Ahl-i Hadith movement has also gained popularity together with Wahhabi influence from the Middle East. The majority of Pakistani Shia Muslims belong to the Twelver Islamic law school, with significant minority groups who practice Ismailism, which is composed of Nizari (Aga Khanis), Mustaali, Dawoodi Bohra, Sulaymani, and others.
