In the name of allah, the Beneficent, the Merciful What is sin in Islam?

THE SLAUGHTERING TOOL

The basic tool to be used in slaughtering is, of course, a knife. Any sharp edge, however, can be used except teeth, nails, or bone. Examples of materials giving a sharp edge are: steel, iron, copper, gold, glass, stone, and wood, if it is sharp enough. Kaab ibn Malik (RA) reported that:

"They had sheep that were shepherded by a young woman who noticed at one point that a lamb was dying. When she told me, I broke a stone and slaughtered it, but I told them not to eat." (The full version is narrated by Al-Bukhari.)
