Sahih Muslim , Book 7, Hadith 3176 (USC-MSA) ⓘ
Abd al-Rahman reported on the authority of his father Abu Sa'id (Allah be pleased with him) that he heard Allah's Messenger as saying: I have declared sacred what is between the two lava grounds of Medina just as Ibrahim (peace be upon him) declared Mecca as sacred. He (the narrator) then said: Abu Sa'id caught hold of (Abu Bakr, another narrator, used the word" found" ) a bird in his hand and then released it from his hand and set it free.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، وَأَبُو كُرَيْبٍ جَمِيعًا عَنْ أَبِي أُسَامَةَ، - وَاللَّفْظُ لأَبِي بَكْرٍ وَابْنِ نُمَيْرٍ - قَالاَ حَدَّثَنَا أَبُو أُسَامَةَ، عَنِ الْوَلِيدِ بْنِ كَثِيرٍ، حَدَّثَنِي سَعِيدُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ عَبْدَ الرَّحْمَنِ، حَدَّثَهُ عَنْ أَبِيهِ أَبِي، سَعِيدٍ أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " إِنِّي حَرَّمْتُ مَا بَيْنَ لاَبَتَىِ الْمَدِينَةِ كَمَا حَرَّمَ إِبْرَاهِيمُ مَكَّةَ " . قَالَ ثُمَّ كَانَ أَبُو سَعِيدٍ يَأْخُذُ - وَقَالَ أَبُو بَكْرٍ يَجِدُ - أَحَدَنَا فِي يَدِهِ الطَّيْرُ فَيَفُكُّهُ مِنْ يَدِهِ ثُمَّ يُرْسِلُهُ .
