Addressing his workers on late Saturday, he said some forces were trying to fan violence in NA-246 ahead of the by-polls on April 23.
The MQM chief, however, refrained from subjecting any political party or leader to criticism.
He asked party supporters and workers to avoid indulging in any violent activity. Even if your rivals pelt stone on you, you must refrain yourself from any retaliation, he preached.
He expressed hope that April 23 will be a historic day and MQM candidate for NA-246 will bag victory in the by-polls.
