Sahih Muslim | Book 9 | Hadith Number 3491

Narrated by Ibn 'Abbas (Allah be pleased with them)
Ibn 'Abbas (Allah be pleased with them) reported that the (pronouncement) of three divorces during the lifetime of Allah's Messenger (may peace be upon him) and that of Abu Bakr and two years of the caliphate of Umar (Allah be pleased with him) (was treated) as one. But Umar b. Khattab (Allah be pleased with him) said: Verily the people have begun to hasten in the matter in which they are required to observe respite. So if we had imposed this upon them, and he imposed it upon them.
