Dividing Bid'ah into Good and Bad, and 'Umar's Statement: "What a Good Bid'ah"

Question:
I say, Honorable Shaykh, may Allah grant you success, what is your view of the one who divides bid'ah (religious innovation) into good and bad, taking this from the statement of 'Umar (may Allah be pleased with him) when he gathered the people for tarawih behind a single imam, saying, "What a good bid'ah this is"?

Answer:
The one who divides bid'ah into good bid'ah and non-good bid'ah is contradicting the statement of the Messenger (peace and blessings be upon him) The Messenger did not corrupt anything; he said, "Every bid'ah is misguidance." This man says, "No, not every bid'ah is misguidance." Is this not a contradiction of the statement of the Messenger (peace and blessings be upon him)? As for 'Umar's statement that this bid'ah is not a religious bid'ah, but rather a bid'ah in the linguistic sense—meaning something that appeared new to the people—the prayer of tarawih was something the people had been accustomed to doing after the Messenger (peace and blessings be upon him) in a scattered manner, or the new thing was that 'Umar gathered them. This new thing is a linguistic bid'ah: he gathered them behind a single imam and returned them to how the matter was during the life of the Messenger (peace and blessings be upon him). He said, "What a good bid'ah this is," because it is in accordance with the Sunnah of the Messenger (peace and blessings be upon him). If a new thing is something the people had forgotten, and one person revives it and restores the Sunnah, it is not called a bid'ah; it is called reviving the Sunnah. These things are Sunnah. The Messenger (peace and blessings be upon him) said, So we say it is a good Sunnah, and we do not say it is perhaps a bid'ah.
