[Machine] The Messenger of Allah, peace be upon him, dug the trench during the Battle of the Confederates until it reached the deep spots. He then cut out forty cubits for every ten people. The emigrants (from Mecca) and the Ansar (from Medina) argued, "Salman is from us!" The Messenger of Allah, peace be upon him, said, "Salman is from us, the household of the Prophet." The authenticity of this narration is weak.
أَنَّ رَسُولَ اللَّهِ ﷺ خَطَّ الْخَنْدَقَ عَامَ حَرْبِ الْأَحْزَابِ حَتَّى بَلَغَ الْمَذَاحِجَ فَقَطَعَ لِكُلِّ عَشَرَةٍ أَرْبَعِينَ ذِرَاعًا فَاحْتَجَّ الْمُهَاجِرُونَ سَلْمَانُ مِنَّا وَقَالَتِ الْأَنْصَارُ سَلْمَانُ مِنَّا فَقَالَ رَسُولُ اللَّهِ ﷺ «سَلْمَانُ مِنَّا أَهْلَ الْبَيْتِ» سنده ضعيف
