Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) made Sayyidah Aisha (may Allah be pleased with her) perform Umrah on the night at the valley of Muhassab after Hajj only to abolish a belief of the polytheists, because they used to say: When the signs of the hardship of travel on the camels disappear after the journey of Hajj, the traces of (the pilgrims’) caravans are erased from the roads, and the month of Safar arrives, then it will be permissible for the one performing Umrah to do Umrah.
