Salam alaikum brothers, lately I have been praying 5 times a day in masjid Alhamdolillah but at the same time I hav been urging/forcing my colleagues for prayer as well sometimes making them feel bad about not praying and I also feel that I am doing a bad thing. I feel I should stop doing this and let them be. Is it right?
You should refrain from indulging in the personal lives of other people. The acceptance and following of religion is a personal matter between an individual and the creator. You as a commoner have no right to force, oppress, intimidate or install the law of Islam, unless you become a rightful caliph, even then your authority would be limited.
You may simply ask them nicely and give an invitation to follow Islam. Accepting or refusing is their choice. As the Quran states:
There shall be no compulsion in the religion. The right course has become clear from the wrong. So whoever disbelieves in evil and believes in Allah has grasped the most trustworthy handhold with no break in it. And Allah is Hearing and Knowing.
Therefore, you should stop making them bad about not praying, because nothing good is ever going to come out from that. Soon they will start despising you and they may also start to despise Islam. This will result in more harm than good.
