٤٣. إِذْ يُرِيكَهُمُ ٱللَّهُ فِى مَنَامِكَ قَلِيلًا ۖ وَلَوْ أَرَىٰكَهُمْ كَثِيرًا لَّفَشِلْتُمْ وَلَتَنَـٰزَعْتُمْ فِى ٱلْأَمْرِ وَلَـٰكِنَّ ٱللَّهَ سَلَّمَ ۗ إِنَّهُۥ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ
[43] And remember the time. O Messenger, when Allah made them appear in your dream as a small band.36 Had He shown them to you as a great army, you would certainly have lost courage and begun to dispute about the matter (the fight). But Allah saved you from this: indeed He known the very secrets of the breasts.
36This happened when the Holy Prophet was marching from Al Madinah towards the battlefield and it was not then known how large the army of the disbelievers was. In this dream, he saw the army and concluded from what he saw that it was not large. He related what he saw in his dream to the Muslims, and this filled them with courage and they marched on boldly towards the enemy.
