(V.2:226) Narrated Nâfi‘: Ibn ‘Umar used to say about Al-’Îla’ (الإيلاء)* which Allâh defined (in the Holy Book), "If the period of Al-’Îla’ (الإيلاء) expires, then the husband has either to retain his wife in a handsome manner or to divorce her as Allâh [عز وجل] has ordered." Ibn ‘Umar added, "When the period of four months has expired, the husband should divorce his wife, but the divorce does not occur unless the husband himself declares it. This has been mentioned by ‘Uthmân, ‘Alî, Abu Ad-Dardâ’, ‘Âishah and twelve other Companions of the Prophet صلى الله عليه وسلم (Sahih Al-Bukhâri, Vol.7, Hadîth No. 213).
* Al-’Îla’ (الإيلاء): means the oath taken by a husband that he would not approach his wife for a certain period.
(V.2:229) Al-Khul‘ * الخلع and how a divorce is given according to it.
Narrated Ibn ‘Abbâs رضي الله عنهما: The wife of Thâbit bin Qais came to the Prophet صلى الله عليه وسلم and said, "O Allâh’s Messenger! I do not blame Thâbit for defects in his character or his religion, but I, being a Muslim, dislike to behave in an un-Islâmic manner (if I remain with him)". On that Allâh’s Messenger صلى الله عليه وسلم said (to her), "Will you give back the garden which your husband has given you as Mahr )?" She said, "Yes." Then the Prophet صلى الله عليه وسلم said to Thâbit, "O Thabît! Accept your garden, and divorce her once." (Sahih Al-Bukhâri, Vol.7, Hadîth No. 197).
* Al-Khul‘ الخلع means the parting of a wife from her husband by giving him a certain compensation.
