question #2 Sahih al-Bukhari 2596, Book 51, Hadith 30 : How did the Prophet Muhammad (ﷺ) handle situations where he could not accept a gift due to religious obligations?

That he heard As-Sa’b bin Jath-thama Al-Laithi, who was one of the companions of the Prophet,
saying that he gave the meat of an onager to Allah’s Messenger (ﷺ) while he was at a place called Al-Abwa’
or Waddan, and was in a state of Ihram. The Prophet (ﷺ) did not accept it. When the Prophet (ﷺ) saw the signs
of sorrow on As-Sa’b’s face because of not accepting his present, he said (to him), “We are not
returning your present, but we are in the state of Ihram.” (See Hadith No. 747)
