Musnad Ahmad 1836Its men are thiqat]
It was narrated that "Ubaidullah bin al-"Abbas said: al-Ghumaisa" - or ar-Rumaisa" - came to the Messenger of Allah (ﷺ) complaining about her husband and claiming that he was not being intimate with her. It was not long before her husband came and claimed that she was lying and that she wanted to go back to her first husband. The Messenger of Allah (ﷺ) said: "You do not have the right to do that until another man (other than your first husband) has tasted your sweetness."
