إِذْ يُرِيكَهُمُ اللَّهُ فِي مَنَامِكَ قَلِيلًا ۖ وَلَوْ أَرَاكَهُمْ كَثِيرًا لَفَشِلْتُمْ وَلَتَنَازَعْتُمْ فِي الْأَمْرِ وَلَٰكِنَّ اللَّهَ سَلَّمَ ۗ إِنَّهُ عَلِيمٌ بِذَاتِ الصُّدُورِ

Surah Al-Anfal : 43
[Remember, O Muhammad], when Allah showed them to you in your dream as few; and if He had shown them to you as many, you [believers] would have lost courage and would have disputed in the matter [of whether to fight], but Allah saved [you from that]. Indeed, He is Knowing of that within the breasts.
