Taking back a wife in a revocable divorce is achieved by words, by scholarly consensus

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on a man who divorced his wife with a revocable divorce and then took her back by words only, without sexual intercourse? Does she return to him, or is sexual intercourse required?

Answer:
She does not return; she returns by words. I took her back, I returned her, and she also returns by sexual intercourse. Both are a taking back. Yes, in fact, the taking back by words is agreed upon by consensus. Yes.
