Read the English translation first, with the original Arabic directly underneath.
Narrated `Abdullah bin `Abbas:
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)
لَيْسَ بِنَا رَدٌّ عَلَيْكَ، وَلَكِنَّا حُرُمٌ
