﴿ يَحْسَبُونَ ٱلْأَحْزَابَ لَمْ يَذْهَبُوا۟ ۖ وَإِن يَأْتِ ٱلْأَحْزَابُ يَوَدُّوا۟ لَوْ أَنَّهُم بَادُونَ فِى ٱلْأَعْرَابِ يَسْـَٔلُونَ عَنْ أَنۢبَآئِكُمْ ۖ وَلَوْ كَانُوا۟ فِيكُم مَّا قَٰتَلُوٓا۟ إِلَّا قَلِيلًۭا ﴾

“They think that the Confederates have not [really] withdrawn; and should the Confederates return, these [hypocrites] would prefer to be in the desert, among the bedouin, asking for news about you, [O believers, from far away;] and even were they to find themselves in your midst, they would but make a pretence at fighting [by your side].”

They suppose that the confederates of disbelievers have not yet departed to Mecca because of their fear of them and were the confederates to come a second time they would wish that they were in the desert with the Bedouins asking about your news your encounters with the disbelievers. And if they were among you this second time they would fight but a little for show and for fear of being reviled.
