is a vast term and many Sufi orders exist within Pakistan where the philosophy has a strong tradition. Historically, the Sufi missionaries had played a pivotal role in converting the native peoples of Punjab and Sindh to Islam. The most notable Muslim Sufi orders in Pakistan are the Qadiriyya, Naqshbandiya, Chishtiya and Suhrawardiyya silsas (Muslim Orders) and they have a large amount of devotees in Pakistan. The tradition of visiting dargahs is still practiced today. Sufis whose shrines receive much national attention are Data Ganj Baksh (Ali Hajweri) in Lahore (ca. 11th century), Sultan Bahoo in Shorkot Jhang, Baha-ud-din Zakariya in Multan, and Shahbaz Qalander in Sehwan (ca. 12th century) and Shah Abdul Latif Bhitai in Bhit, Sindh and Rehman Baba in Khyber Pakhtunkhwa Province. The Urs (death anniversary) of Sufi saints accounts for the largest gathering upon their shrines held annually by the devotees. Although, popular Sufi culture is centered on Thursday night gatherings at shrines and annual festivals which feature Sufi music and dance, certain tariqas such as Sarwari Qadri Order, refrain from such traditions and believe in paying visit to the shrines, making prayers or reciting manqabat. Moreover, contemporary Islamic fundamentalists also criticize the popular tradition of singing, dance and music, which in their view, does not accurately reflect the teachings and practice of Mohammad and his companions. There have been terrorist attacks directed at Sufi shrines and festivals, five in 2010 that killed 64 people. Presently, the known tariqas in Pakistan have maintained their organisations usually known as tehreeks and have their khanqahs for the dhikr of Allah, as per the old age Sufi tradition. Quranists Muslims who reject the authority of hadith, known as Quranist, Quraniyoon, or Ahle Quran, are also present in Pakistan. The largest Quranist organization in Pakistan is Ahle Quran, followed by Bazm-e-Tolu-e-Islam. Another Quranist movement in Pakistan is Ahlu Zikr. Nondenominational Roughly twelve per cent of Pakistani Muslims self-describe or have beliefs overlapping with non-denominational Muslims. These Muslims have beliefs that by and large overlap with those of the majority of Muslims and the difference in their prayers are usually non-existent or negligible. Nonetheless, in censuses asking for a clarification on which strand or rite of Muslim faith they most closely align, they usually answer "just a Muslim".
