After coming to Madinah Munawwarah, Hazrat Mus’ab bin Umair (radhiyallahu ‘anhu) would invite the people towards Islam and lead them in Salaah as he was their imaam.

One day, Hazrat Mus’ab (radhiyallahu ‘anhu) was delivering a sermon and inviting towards Islam in front of a large crowd of people. On hearing of this, Usaid bin Hudhair immediately picked up his sword, came to him and said, “What have you come here for? Why are you misleading our women and children? It would be better if you left this place!”
