Prophet Mohammad( Salla-llahu A’liahi wa sallam) sent one men to Yathrib (Madinah). There Mus’ab planted the seeds of knowledge among the first Muslims. He strengthened their faith by teaching them the few revealed verses of the Qur’an. Along with Mus’ab the new Muslims worked endlessly to spread the message of Islam to the entire city of Yathrib. By the time the Prophet (May Peace Be Upon Him) migrated to Medinah there stood 8000 Muslims at the gates of the city ready to welcome him, and First state was established with word of love and convection only.
