The Meaning of the Hadith: Whoever Introduces a Good Practice in Islam

Question:
He says: May Allah reward you, what is the meaning of the hadith ? For the innovators use it as evidence for the validity of their religious innovations (bid'ah)?

Answer:
It means he revived a sunnah (recommended practice), not that he invented something unknown. Its meaning is that he revived a sunnah. The reason for the hadith, which they mentioned, clarifies this. A group of poor people came asking the Messenger (peace and blessings be upon him) for assistance. So the Messenger (peace and blessings be upon him) called the people to prayer. When they had completed the prayer, he (peace and blessings be upon him) ordered charity to be given to these people. Everyone came with what they could afford; some came with a handful of dates, some with a dirham, and some with... Then a man came with a bundle of gold, so heavy that his hand almost failed to carry it. He placed it before the Messenger (peace and blessings be upon him).
The people followed one another when they saw this man, and they increased their charity. Then he (peace and blessings be upon him) brightened in face, and said: , . So this man revived the sunnah, and the people followed him. Charity for the needy is not an innovation; this is an old sunnah, which Allah ordered and the Messenger (peace and blessings be upon him) ordered.
So the meaning of is that he revived a sunnah that the people had forgotten or abandoned. Yes.
