قَالَ مَالِكٌ : وَإِنْ خَيَّرَهَا فَقَالَتْ : قَدْ قَبِلْتُ وَاحِدَةً وَقَالَ : لَمْ أُرِدْ هَذَا، وَإِنَّمَا خَيَّرْتُكِ فِي الثَّلَاثِ جَمِيعًا، أَنَّهَا إِنْ لَمْ تَقْبَلْ إِلَّا وَاحِدَةً، أَقَامَتْ عِنْدَهُ، وَلَمْ يَكُنْ ذَلِكَ فِرَاقًا .
Imam Malik, may Allah have mercy on him, said: And if her husband gives her the choice and she says, "I have accepted one divorce," and the husband says, "I did not mean the option of one divorce, I only gave you the option of three divorces together," then (in this case) undoubtedly, if the woman does not accept anything except one, (she will not be divorced at all) she will remain with her husband and this (action among them) will not be a cause of separation.
SA Benefit: EA According to all other Imams and Ahl al-Hadith except Imam Malik, may Allah have mercy on him, in the mentioned case, one divorce will take place.
