Imam Ali-ul-Haq, better known as Imam Sahib, lived in the 13th century, during the reign of Feroz Shah Tughlaq (of the Tughlaq Dynasty). He is reputed to have converted a majority of the local population of Sialkot to Islam. Imam Sahib battled against Raja of Sialkot and martyred. Hazrat Imam Ali ul Haq's shrine is also situated in Sialkot city at the place where he was martyred. The path leading to the tomb is often lined with numerous prostrating pilgrims. The mausoleum complex is a maze of narrow corridors leading to several shrines of pirs (holy men). The tomb of Imam Ali-ul-Haq is to the right, through a mirrored gateway tiled with Quranic inscriptions and geometric designs. The courtyard is a place to sit and absorb the atmosphere. To the rear is a small graveyard where drumming, devotional singing and dancing takes place. The market outside is very photogenic and a large flat roof at the entrance to the shrine offers a panoramic view of the deals being struck.
Imam Ali ul Haq was the 14th Caliph of Hazrat Ganj Shaker. Hazrat Ganj Shaker lived his life during the reign of Emperor Bulban, therefore this source shows that Imam Sahib was from the era of Emperor Bulban. Both the emperors have time difference of 90 years. However, some other sources show that Imam Sahib participated in numerous holy wars during the era of Emperor Taghaluq, therefore as a whole, it can be said that Imam Sahib most probably lived his life during the time of Emperor Taghaluq.
