Allah's Messenger (ﷺ) gave us the option (to get divorce) but we did not deem it as divorce.
Sahih Muslim Book 18, Hadith 33
← Previous Hadith The above hadith has likewise been narrated through another chain.

Sahih Muslim Book 18, Hadith 32 Next Hadith → I do not mind if I give option to my wife (to get divorce) once, hundred times, or thousand times after (knowing it) that she has chosen me (and would never seek divorce). I asked 'A'isha (Allah be pleased with her) (about it) and she said: Allah's Messenger (ﷺ) gave us the option, but did it imply divorce? (It was in fact not a divorce; it is effective when women actually avail themselves of it.)
