Musannaf Ibn Abi Shaybah 20059 — If he gives her a revocable divorce

Sa'id (may Allah have mercy on him) said: When a man has given his wife one divorce, he will seek permission before coming in to her. The woman, however, may wear whatever clothes and jewellery she wishes. If the two of them have only one room, they should put a screen between them, and the man should greet with salam before coming in.
