Is it allowed to do so from shariath point of view?(inviting to islam)
Your question is unclear. Are you requiring the permissibility of going out
in Jamaat?
If so, then, we wish to advise you that going out in Jamaat is a noble work
and a great Sunnah of Rasulullah (Sallallaahu Alayhi Wasallam) and all the
prophets. Every prophet of Allah invited their people to believe in Allah
and in the Oneness of Allah. Hadhrat Ali (Radhiallaahu Anhu) said, ‘If one
person is guided through you, that is better than red camels (most
prestigious commodity of that time)
You should consult a senior person, preferably an Aalim who is actively
engaged in Tabligh. He will advise you according to your personal
circumstances. The seniors in Da’awah and Tabligh encourage people to go out
in the path of Allah, but also take into cognizance one’s personal
circumstances as well.
and Allah Ta’ala Knows Best
