“(And remember) when Allah showed them to you as few in your dream; if He had shown them to you as many, you would surely have been discouraged…” [Qur’an 8:44]
Hafiz ibn Kathir relates in his Tafsir: Mujahid said, “In a dream, Allah showed the Prophet the enemy as few. The Prophet conveyed this news to his Companions and their resolve strengthened.” This demonstrates Allah’s compassion towards the believers. Allah made them see few disbelievers in their eyes, so that they would be encouraged and feel eager to meet them.
