لَوْ خَرَجُوا۟ فِيكُم مَّا زَادُوكُمْ إِلَّا خَبَالًا وَلَأَوْضَعُوا۟ خِلَـٰلَكُمْ يَبْغُونَكُمُ ٱلْفِتْنَةَ وَفِيكُمْ سَمَّـٰعُونَ لَهُمْ ۗ وَٱللَّهُ عَلِيمٌۢ بِٱلظَّـٰلِمِينَ
Asad Quran Translation
Had these [hypocrites] set out with you, [O believers,] they would have added nothing to you save the evil of corruption, and would surely have scurried to and fro in your midst, seeking to stir up discord among you, seeing that there are in your midst such as would have lent them ear: but God has full knowledge of the evildoers.
Malik Quran Translation
Had they gone with you they would have added nothing but mischief, and they would have made efforts to create disorder among your ranks, and there would have been some among you who would have listened to them. Allah knows the wrongdoers.
Yusuf Ali Quran Translation
If they had come out with you they would not have added to your (strength) but only (made for) disorder hurrying to and fro in your midst and sowing sedition among you and there would have been some among you who would have listened to them. But Allah knoweth well those who do wrong. 1310
Khilal has more than one meaning, but I follow the interpretation of Ragib and the majority of accepted Commentators, who take it to mean "in your midst".
Mustafa Khattab Quran Translation
Had they gone forth with you ˹believers˺, they would have been nothing but trouble for you, and would have scrambled around, seeking to spread discord in your midst. And some of you would have eagerly listened to them. And Allah has ˹perfect˺ knowledge of the wrongdoers.
Piktal Quran Translation
Had they gone forth among you they had added to you naught save trouble and had hurried to and fro among you, seeking to cause sedition among you; and among you there are some who would have listened to them. Allah is Aware of evil-doers.
