33:18 · Al-Ahzaab
قَدْ يَعْلَمُ اللَّهُ الْمُعَوِّقِينَ مِنْكُمْ وَالْقَائِلِينَ لِإِخْوَانِهِمْ هَلُمَّ إِلَيْنَا ۖ وَلَا يَأْتُونَ الْبَأْسَ إِلَّا قَلِيلًا
Verily Allah knows those among you who keep back (men) and those who say to their brethren, "Come along to us", but come not to the fight except for just a little while.
