كتاب الطلاق
Read the English translation first, with the original Arabic directly underneath.
Expiation must be offered by one who declares his wife to be unlawful for him but does not intend divorce thereby
Ibn Umar (Allah be pleased with them) reported:
I divorced my wife during the lifetime of Allah's Messenger (ﷺ) when she was in the state of menses. 'Umar (Allah be pleased with him) made a mention of it to Allah's Messenger (ﷺ), whereupon he said: Command him to take her back and leave her (in that state) until she is purified. Then (let her) enter the period of second menses, and when she is purified, then divorce her (finally) before having a sexual intercourse with her, or retain her (finally). That is the 'Idda (the prescribed period) which Allah commanded (to be kept in view) while divorcing the women. 'Ubaidullah reported: I said to Nafi': What became of that divorce (pronounced within 'Idda)? He said: It was as one which she counted.
مُرْهُ فَلْيُرَاجِعْهَا ثُمَّ لْيَدَعْهَا حَتَّى تَطْهُرَ ثُمَّ تَحِيضَ حَيْضَةً أُخْرَى فَإِذَا طَهُرَتْ فَلْيُطَلِّقْهَا قَبْلَ أَنْ يُجَامِعَهَا أَوْ يُمْسِكْهَا فَإِنَّهَا الْعِدَّةُ الَّتِي أَمَرَ اللَّهُ أَنْ يُطَلَّقَ لَهَا النِّسَاءُ
