The Arain (Punjabi, Urdu: آرائین), are a Muslim agricultural caste settled mainly in the Punjab, with significant numbers also in Sindh. They are chiefly associated with farming, traditionally being landlords or zamindars.

In the Punjab Census Report (1911), Pandit Harikishan Kaul points out that members of the Arain tribe are “mostly Muhammadans,” (in the Glossary of the Tribes and Castes of the Punjab and North West Frontier Province, Denzil Ibbetson also refers to the Arains as, “Almost to a man Muhammadans”), and as a corollary, reference is also made to Hindu and Sikh sections of the tribe which make up 3% of Arains, with 97% Sunni Muslims.

Kaul also states that the term ‘Arain’ is, “derived probably from Rain or Rahin, equivalent to Rahak (tiller of soil).” This is consistent with the Arains traditionally being chiefly associated with market-gardening.

Some Arain however propose descent from Arabs belonging to Muhammad bin Qasim's expeditionary force to India. Such claims are given credance by how nearly all Arain are, and have been, Sunni Muslim, much like the early Arabs accompanying Muhammad bin Qasim. This assertion is supported by numerous references made in several Urdu language texts; Tareekh-e-Arain, Sham Ta Multan, Tareekh Frishta, Tohfa Tul Ikram and Aina-e-Haqeekat Numa, that reliably trace the lineage of many notable Arain including Zia Ul-Haq and the famous Mian Family of Bhaghbanpura. According to these sources, the word Arain is derived from Areeha which is the Arabic name for the city of Jericho in the West Bank, Palestinian Territory, the place from where they allegedly came.

Ch Muhammad Ijaz-ul-Haq (Punjabi, Urdu: محمد اعجاز الحق) (born 1953) is a prominent Pakistani politician and a businessman who served as a Federal Minister for Religious Affairs and Minorities under the Government of Prime minister Shaukat Aziz. A former Pakistan Army officer, Haq joined the Pakistan Army in 1971, as second lieutnenat, but he left during his term as a Captain. Originally a Bahrain-based banker, Ijaz entered national politics following the assassination of his father, Military President General Zia-ul-Haq, in 1988. He rose to prominence in the Pakistan Muslim League as a right-wing opponent of the succeeding Benazir Bhutto's government. He was appointed Federal minister for Labour within the cabinet of Zia's civilian successor Nawaz Sharif as well as the senior president of the Pakistan Muslim League (N) during its second tenure in the 1990s. He stepped down from the post following differences with Sharif, who was overthrown shortly afterwards by General Pervez Musharraf in 1999.

Nawaz Sharif (Punjabi, Urdu: نواز شریف; born December 5, 1949) is a Pakistani steel magnate and national conservative, serving as the 12th Prime Minister of Pakistan in two non-consecutive terms from November 1990 to July 1993, and from February 1997 until October 12, 1999. He is the President of the Pakistan Muslim League-N, the Centre-right-conservative political force in Pakistan.

Before becoming the Prime minister, Sharif served as the ninth Chief Minister of Punjab Province from 1985 to 1990 and embarked his political career under the military regime of President General Zia-ul-Haq. An advocate and businessman, he owns Ittefaq Group, a private steel mill enterprise and one of the largest producer of iron materials, noted as being as Pakistan's one of the wealthiest investor in the steel mill business. His political philosophy emphasized and reflected conservatism advocating for the free-market economy, capitalism as its economic base. His first term survived a serious constitutional crisis when President Ghulam Ishaq Khan attempted to dismissed Sharif by citing "corruption and nepotism", which Sharif strongly denied and turned to Supreme Court. The apex Supreme Court of Pakistan favored the Prime minister citing that Presidential ordnance as "unconstitutional and irrelevant", therefore the government was reconstituted. His first term was finally dismissed after the Pakistan Armed Forces persuaded him to resign to end the political standoff with President Ishaq Khan, which he too was forced to resigned.
