[1] Ul Haq was born in Jhang District in Punjab, Pakistan to a Kashmiri street vendor and watermelon seller.

He was granted German citizenship in 2001, moved to Offenbach and ran a cell phone shop with a postal agency in Frankfurt-Nordend.

[9][10][11][12][13] In his book, "Die Brutstätte des Terrors", he detailed his findings and experiences and claimed that inadequate living conditions and lack of opportunities to indulge in religious practices, and long waits for asylum decisions were leading to the radicalization of refugees by Islamists.

[18][19][20] Haq also conducted undercover reporting work in European mosques investigating Islamic radicalization.

[21][22][23][24] In 2020, Haq and his colleague Susana Santina produced a behind the scenes documentary about deradicalization centres in Pakistan and the former militants who were kept at these camps.
