(30) بَابُ مَرْجَعِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنَ الأَحْزَابِ وَمَخْرَجِهِ إِلَى بَنِي قُرَيْظَةَ وَمُحَاصَرَتِهِ إِيَّاهُمْ
Narrated `Aisha:
When the Prophet (ﷺ) returned from Al-Khandaq (i.e. Trench) and laid down his arms and took a bath, Gabriel came and said (to the Prophet (ﷺ) ), You have laid down your arms? By Allah, we angels have not laid them down yet. So set out for them." The Prophet (ﷺ) said, "Where to go?" Gabriel said, "Towards this side," pointing towards Banu Quraiza. So the Prophet (ﷺ) went out towards them.
