وَعَنْ مَكْحُولٍ; { أَنَّ اَلنَّبِيَّ - صلى الله عليه وسلم -نَصَبَ اَلْمَنْجَنِيقَ عَلَى أَهْلِ اَلطَّائِفِ } أَخْرَجَهُ أَبُو دَاوُدَ فِي
"اَلْمَرَاسِيلِ"
Makhul (RAA) narrated, ‘The Messenger of Allah (ﷺ) set up the ballista while attacking the people of at-Ta’if`.’ Related by Abu Dawud with a trustworthy chain of narrators, but it is hadith Mursal.
