قَالُوا۟ يَٰمُوسَىٰٓ إِنَّ فِيهَا قَوْمًۭا جَبَّارِينَ وَإِنَّا لَن نَّدْخُلَهَا حَتَّىٰ يَخْرُجُوا۟ مِنْهَا فَإِن يَخْرُجُوا۟ مِنْهَا فَإِنَّا دَٰخِلُونَ
They said: O Moses! Lo! a giant people (dwell) therein and lo! we go not in till they go forth from thence. When they go forth from thence, then we will enter (not till then).
