Religions

Census data indicates that over 98% of the population are Muslims. The Muslims are divided into different sects which are called schools of jurisprudence i.e. 'Maktab-e-Fikr' (School of Thought) in Urdu. Nearly 80% of Pakistani Muslims are Sunni Muslims and 20% are Shi'a Muslims. The nearly all Pakistani Sunni Muslims belong to Hanafi school with a small Hanbali school represented by Wahabis and Ahle Hadith. The Hanafi school is divided into Barelvis and Deobandis schools. While majority of Pakistani Shia Muslims belong to Ithna 'ashariyah school with significant minority of Nizari Khoja Ismailis (Aga Khanis) and a small Mustaali Dawoodi Bohra schools. By one estimate, in Pakistan, Muslims are divided into following schools: the Barelvis 48%, Deobandis 25%, Ithna Ashari 19%, Ahle Hadith 4%, Ismailis 1%, Bohras 0.25%, and other smaller sects. The Ahle-e-Hadith are part of Hanbali school. Nearly 65% of the total seminaries (Madrassah) are run by Deobandis, 25 per cent by the Barelvis, six percent by the Ahle Hadith and three percent by various Shia organizations. Zikris are considered to be a heretical sect by mainstream Muslims.

The non-Muslim population mainly comprises of Christians (1% of the population) and Hindus (1%), with smaller numbers of Ahmadis, Buddhists, Jews, Sikhs, Zoroastrians, and Animists (mainly the Kalash in Chitral). Pakistan's religious demographics has been significantly influenced by the movement of populations in 1947 (millions of Muslims moved to Pakistan and millions of Hindus and Sikhs moved to India) and the wars in Afghanistan (millions of refugees who have become permanent residents).

Although there are very few Sikhs in Pakistan today, the country has a significant place in Sikhism. Guru Nanak, the founder of Sikhism was born in present-day Pakistan, and it is said he received his message near Lahore. Therefore, the religion actually originated in Pakistan. Most of Sikhism's holy sites are located in Pakistan. Many other great Sikh leaders, including Ranjit Singh and several gurus, were born in Pakistan. Ranjit Singh is buried in Lahore.

Pakistan is also the birthplace of Mahayana Buddhism, the form of Buddhism that is practiced by most Buddhists today, including those in India, Japan, China, Korea, and Vietnam. The religion enjoyed prominence in the northwestern section of the country up until the arrival of Islam.

Islam was brought to the South Asian subcontinent in the eighth century by wandering Sufi mystics known as pir. As in other areas where it was introduced by Sufis, Islam to some extent syncretized with preIslamic influences, resulting in a religion traditionally more flexible than in the Arab world. Two Sufis whose shrines receive much national attention are Data Ganj Baksh in Lahore (ca. eleventh century) and Shahbaz Qalander in Sehwan, Sindhh (ca. twelfth century).
