Hazrat Ibn Umar radiyallahu anhuma reports, "When Rasoolullah sallallahu alaihe wasallam fastened an amaamah (turban), he used to put the shamlah between his shoulers (i.e. he used to put it on the back)."Nafi says, "I had seen Abdullah bin Umar radiyallahu anhuma do it in the same manner."Ubaidullah, who is the student of Nafi, says, "In my time the grandson of Abu Bakr radiyallahu anhu, Qasim bin Muhammad and the grandson of Umar radiyallah anhu, Saalim bin Abdullah did the same.
