وعليكم السلام ورحمة الله وبركاته Tell them that if that was true , then the Prophet صلى الله عليه وسلم would have informed us about it . Rather he married Safiyya in the month of Muharram and it was a famous and a well-known feast and the Muslims were greatly happy during that . In that month , the ruling of Hijab was revealed and the Muslims rejoiced in that too. All months are for Allah عز وجل , and no one can prevent what is permissible in them except with evidence. And Allah عز وجل knows best .
