It is narrated from Hazrat Abu Bakrah (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) came to a people who were handing naked swords to one another. The Prophet (peace and blessings be upon him) said, "The curse of Allah is upon those who do this. Did I not forbid you from this?" Then he said, "When any one of you draws a sword, he should see that if he intends to hand it to his brother, he should put it in its sheath and then hand it to him."
