Battles (Kitab Al-Malahim)
39/17. Chapter:
Command And Prohibition
Sunan Abi Dawud
حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا أَبُو شِهَابٍ، عَنْ مُغِيرَةَ بْنِ زِيَادٍ، عَنْ عَدِيِّ بْنِ عَدِيٍّ، عَنِ النَّبِيِّ صلى الله عليه وسلم نَحْوَهُ قَالَ " مَنْ شَهِدَهَا فَكَرِهَهَا كَانَ كَمَنْ غَابَ عَنْهَا " .
A similar tradition has also been transmitted by ‘Adl from the prophet (ﷺ) though a different chain of narrators. This version has : He who sees it and disapproves of it will be like him who was not present.
