What did the Prophet Muhammad (peace be upon him) do when his hair was matted and he had garlanded his Hadi, that prevented him from finishing his Ihram?
 Narrated Hafsa:                     I said, "O Allah's Apostle! What is wrong with the people, they have finished their Ihram but you have not?" He said, "I matted my hair and I have garlanded my Hadi, so I will not finish my Ihram till I finished my Hajj ."
