The Representatives of this department of Dawat-e-Islami are tasked with the job of going into various jails/prisons and spending time with prisoners of different backgrounds. The aim for such meetings being the reformation of prisoners in such a way that when they are released from prison they can live as law-abiding citizens who will make a positive contribution to society. Many ex-convicted criminals have now been reformed through the efforts of Prisoner Reform department of Dawat-e-Islami and are now contributing positively to their respective societies.

Dawat-e-Islami also arranges courses for prisoners by means of which they can gain basic education and life skills which help them stay away from crime and misconduct upon release. Many of them have joined Dawat-e-Islami in its noble cause and now actively volunteer for Dawat-e-Islami.

This department of Dawat-e-Islami UK has also quite a few successful stories where ex-convicted criminals have changed and are living as law abiding citizens of United Kingdom.
