Plain UnderstandingGod swears by the intense, dynamic energy of loyal war horses that gallop so furiously they pant, strike sparks from the rocks, attack at the break of dawn, and fearlessly plunge directly into the center of the enemy ranks.
Historical Context (Ibn Kathir)Allah swears by the horses when they are made to gallop into battle in His path (Jihad). The sparks fly from their hooves, and they attack at dawn just as the Prophet ﷺ used to wait for the break of dawn to initiate his campaigns, bringing light to the darkness of oppression.
Purification of the Self (Al-Jilani)Look at the profound loyalty of the animal. It plunges into swords and spears, risking its own life out of pure obedience to its human master, who merely provides it with some hay and water. Yet man, who is continuously showered with infinite blessings by the Lord of the Worlds, refuses to show even a fraction of that loyalty and courage for his Creator.
