Quote from Wiki : http://en.wikipedia.org/wiki/Abdul-Qadir_Gilani :
Stays in Lahore and Amritsar
He left his home in 908 of Hijra and came to Lahore where he spent some years in preaching. A lot of people from Lahore, in particular, and Punjab, in general, embraced Islam on his hands, and became his followers. Even today one can find many of his descendants in Pir Kot and Lahore. He then went to Amritsar, and spent somewhat equal amount of time there. .......
From Amritsar, probably in 920 of Hijra, he came to Batala and stayed at place called Mian Muhalla. He spent some years in ibaadat and tableegh in Mian Muhalla, and then .......He was over fifty years old by the time he returned to Baghdad in 1127, and began to preach in public. He died at the age of 91 years, and rests in a shrine within his Madrassa in Baghdad
