Hadees
Volume 2, Book 26, Number 635:
Narrated Ibn Abbas:
The people (of the Pre-lslamic Period) used to think that to perform 'Umra during the months
of Hajj was one of the major sins on earth. And also used to consider the month of Safar as a
forbidden (i.e. sacred) month and they used to say, "When the wounds of the camel's back
heal up (after they return from Hajj) and the signs of those wounds vanish and the month of
Safar passes away then (at that time) 'Umra is permissible for the one who wishes to perform
it." In the morning of the 4th of Dhul-Hijja, the Prophet and his companions reached Mecca,
assuming Ihram for Hajj and he ordered his companions to make their intentions of the Ihram
for'Umra only (instead of Hajj) so they considered his order as something great and were
puzzled, and said, "O Allah's Apostle! What kind (of finishing) of Ihram is allowed?" The
Prophet replied, "Finish the Ihram completely like a non-Muhrim (you are allowed
everything)."
