Sahih al-Bukhari, Hadith 1844 ⓘ
Narrated Al-Bara: The Prophet assumed Ihram for Umra in the month of Dhul-Qa'da but the (pagan) people of Mecca refused to admit him into Mecca till he agreed on the condition that he would not bring into Mecca any arms but sheathed.
حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ إِسْرَائِيلَ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ ـ رضى الله عنه ـ اعْتَمَرَ النَّبِيُّ صلى الله عليه وسلم فِي ذِي الْقَعْدَةِ، فَأَبَى أَهْلُ مَكَّةَ أَنْ يَدَعُوهُ يَدْخُلُ مَكَّةَ، حَتَّى قَاضَاهُمْ لاَ يُدْخِلُ مَكَّةَ سِلاَحًا إِلاَّ فِي الْقِرَابِ.
