It is narrated from Hazrat Jarir (may Allah be pleased with him) that some people came who were barefoot, naked, wrapped in leopard skins, and had swords hanging by their sides. The Holy Prophet (peace and blessings be upon him) encouraged the people to give charity, but the people delayed, upon which the color of the blessed face of the Holy Prophet (peace and blessings be upon him) changed. Then an Ansari man came with a piece of silver and put it down. After that, people began to come continuously. The face of the Holy Prophet (peace and blessings be upon him) began to shine, and it seemed as if it was made of gold. He said: Whoever introduces a good practice in Islam, he will have its reward and the reward of those who act upon it after him, without their rewards being diminished in the least. And whoever introduces a bad practice in Islam, he will bear its sin and the sin of those who act upon it after him, without their sins being diminished in the least.
