Praise be to Allah the Lord of the Worlds.The woman observing Iddah following divorce or death of husband isn`t allowed to travel for no necessity, as agreed by the majority of the scholars. Al-Shirbini says, "She isn`t allowed to leave for business, social visits and Hajj, because they aren`t a necessity."{Moghni Al-Mohtajj, 3/402}. And Allah the Almighty knows best.
