Re: Punjab before Muslim Invasions
Wiki uncle says that:
**
Al-Hujwiri came to Lahore under orders from his Pir as successor to Shaikh Husain Zanjani at a time when as a result of irruption of the Seljuks on one side and the rising tide of Hindu resistance on the order, the Ghaznavid Empire began to dismember rapidly, and life in Ghazni itself was disrupted. The saint had to leave Ghazni in difficult circumstances, leaving his books behind. According to Faw’id-ul-Fu’ad, Ali Hujwiri reached Lahore at night and in the morning found the people bringing out the bier of Shaikh Husain Zanjani whom he replaced in Lahore**
This means Muslims had presence in Lahore before Ghaznavi period due t sufi saints.
