Sahih muslim:1353b Chapter: What one who has entered Ihram for Hajj or Umrah is permitted to wear, and what is not permissible, and perfume is forbidden for him Book 15, Hadith 507

A hadith like this has been narrated on the authority of Mansur, but he did not mention: ” On that very day He created the heavens and the earth,” and he (the narrator) substituted the word” fighting” (qital) for” killing” (qatl), and further said:” No one is to pick up the dropped thing except one who makes a public announcement of it.”
