On the day of Badr, some Arabs were sitting on a mountain saying: "We are with the one who prevails." When Allah granted victory to the Messenger of Allah (peace be upon him), they came and said: "O Messenger of Allah! We heard something descending from the sky, the neighing of horses and the clanking of equipment, and we heard a voice: 'Advance, Haizum!'" The Messenger of Allah (peace be upon him) said: "That was our master Jibreel (Gabriel), peace be upon him."
