Surah Al-Fath Verse 16

قُل لِّلْمُخَلَّفِينَ مِنَ الْأَعْرَابِ سَتُدْعَوْنَ إِلَىٰ قَوْمٍ أُولِي بَأْسٍ شَدِيدٍ تُقَاتِلُونَهُمْ أَوْ يُسْلِمُونَ ۖ فَإِن تُطِيعُوا يُؤْتِكُمُ اللَّهُ أَجْرًا حَسَنًا ۖ وَإِن تَتَوَلَّوْا كَمَا تَوَلَّيْتُم مِّن قَبْلُ يُعَذِّبْكُمْ عَذَابًا أَلِيمًا

Qul lilmukhallafeena minal A'raabi satud'awna ilaa qawmin ulee baasin shadeedin tuqaati loonahum aw yuslimoona fa in tutee'oo yu'tikumul laahu ajran hasananw wa in tatawallaw kamaa tawallaitum min qablu yu'azzibkum 'azaaban aleemaa

Translation / The Meaning

Say to those who remained behind of the bedouins, "You will be called to [face] a people of great military might; you may fight them, or they will submit. So if you obey, Allah will give you a good reward; but if you turn away as you turned away before, He will punish you with a painful punishment."
