Did the marriage between Umm Kulthum and Omar ibn Al-Khattab happen?

Answer

In the name of Allah, we have stated in various answers that the claim of the marriage of of Ali ibn Abi Talib's daughter (PBUH) is fabricated, and our righteous scholars, including the esteemed researcher, the great scholar, Syed Ja'far Murtada Al-'Amili (may his soul be sanctified), have confirmed this in his book "The Obscurity of Umm Kulthum: Investigation and Study." Allah is the Guide.
