Terror is a great tool which the Muslims asked for in their supplications against the disbelievers.

Yazeed ibn ‘Aamir, (May Allaah be pleased with him), was amongst the ranks of the disbelievers during the battle of Hunayn;

When he later became Muslim, some of the Companions, (may Allah be pleased with them), asked him:

“How was the nature of this terror which Allah instilled in the hearts of the disbelievers? Describe it for us.”

Thereupon, he, (May Allah be pleased with him), grabbed a stone and flung it strongly against a metal pot, which caused a very loud noise, and remarked:

“This is how we felt horror in our hearts.”
