It is narrated from Sayyiduna Hudhayfah (may Allah be pleased with him): We were with the Prophet (peace and blessings be upon him) when a beggar stood before us. The people remained silent. He asked again, and some of the people gave him a ring or something else; then the others followed one after another and gave to him. Then the Messenger of Allah (peace and blessings be upon him) said: "Whoever initiates a good practice and is followed in it will have his own reward and the like of the rewards of those who follow him in it, without anything being reduced from their rewards. And whoever initiates an evil practice and is followed in it will bear its burden and the like of the burden of those who follow him in it, without anything being reduced from their burdens."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Khalid al-Hadhdha' except Ali bin Asim."
