Muslims see everything bestowed on them as a blessing by Allah. However, among them, Bread takes a different place. It is perhaps the simplest of food, the easiest to obtain, and the food most wanted by anyone living in the world.
For this reason, Muslims never leave the bread on the ground, and when they see a bread on the ground, they definitely put it in a high place.
They see it as disrespect for this blessing bestowed on the ground. that is, they regard it as disrespect to Allah.
