5فَإِذا جاءَ وَعدُ أولاهُما بَعَثنا عَلَيكُم عِبادًا لَنا أُولي بَأسٍ شَديدٍ فَجاسوا خِلالَ الدِّيارِ ۚ وَكانَ وَعدًا مَفعولًا(Irfan-ul-Quran)So when the promised first time of the two came to pass We brought upon you those of Our servants who were great warriors. Then, in (your) search they penetrated up to your dwellings. And (this) promise was sure to be fulfilled.
