Q: There are some misconceptions that it's not good to start a business in Muharram and Safar. Is it true in the light of Islam or do people just say it out of respect of this month?
A. This is not respect for Muharram and Safar but pure superstition. Do not believe or follow this superstition.A Hadeeth of Saheehul-Bukhaari states: “There should be no superstition about Safar” (Laa Safara) The Arabs also had these false and superstitious beliefs about the month of Safar, that is why The Messenger of Allah (Sallallaahu Alayhi wa Sallam) mentioned this in particular. The superstitions about Muharram were fabricated by the Shias.
