Abu al-Ahwas (may Allah have mercy on him) said: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said concerning the verse "O Prophet! When you divorce women, divorce them for (the time of) their waiting period" [Surah al-Talaq: 1]: "Divorce for the waiting period is that you divorce her in a state of purity, then leave her until she completes her waiting period, or take her back if you wish." Shu'bah said: "And the people of Kufah say: without intercourse."
