Sharia law (Arabic: شريعة‎ šarīʿah, IPA: [ʃaˈriːʕa], "legislation"; sp. shariah, sharīʿah; also Islamic law, قانون إسلامي qānūn ʾIslāmī) is the moral code and religious law of Islam. Sharia deals with many topics addressed by secular law, including crime, politics and economics, as well as personal matters such as sexual intercourse, hygiene, diet, prayer, and fasting. Though interpretations of sharia vary between cultures, in its strictest definition it is considered the infallible law of God—as opposed to the human interpretation of the laws (fiqh).

There are two primary sources of Islamic law: the precepts set forth in the Quran, and the example set by the Islamic prophet Muhammad in the Sunnah. Where it has official status, sharia is interpreted by Islamic judges (qadis) with varying responsibilities for the religious leaders (imams). For questions not directly addressed in the primary sources, they extend the application of sharia through consensus of the religious scholars (ulama) thought to embody the consensus of the Muslim Community (ijma). Islamic jurisprudence will also sometimes incorporate analogies from the Quran and Sunnah through qiyas, though Shia jurists prefer reasoning ('aql) to analogy.

Zakir Abdul Karim Naik (Urdu: ذاکر عبدالکریم نائیک; born 18 October 1965) is an Indian public speaker on the subject of Islam and comparative religion. He is the founder and president of the Islamic Research Foundation (IRF), a non-profit organisation that owns the Peace TV channel based in Dubai, UAE. He is sometimes referred to as a televangelist. Before becoming a public speaker, he trained as a doctor. He has written two booklets on Islam and comparative religion. He is regarded as an exponent of the Salafi ideology; he places a strong emphasis on individual scholarship and the rejection of "blind Taqlid", which has led him to repudiate the relevance of sectarian or Madh'hab designations, all the while reaffirming their importance.

Zakir Abdul Karim Naik was born on 18 October 1965 in Mumbai, India. He attended St. Peter's High School in Mumbai. Later he enrolled at Kishinchand Chellaram College, before studying medicine at Topiwala National Medical College and Nair Hospital and later the University of Mumbai, where he obtained a Bachelor of Medicine and Surgery (MBBS). His wife, Farhat Naik, works for the women's section of the IRF.
