Is it permissible to take back one's wife after the husband said to her, "You are unlawful to me" without intending divorce, then "You can consider yourself divorced" as a threat, and then said to her brother "Divorce" without finalizing the matter, knowing that he fed sixty poor people for his first statement?

If a man says to his wife, "You are unlawful to me," and he intends ẓihār (a pre-Islamic form of divorce), then he must offer the expiation for it. If he is unable to fast for two consecutive months, he is permitted to feed [the poor], provided that his inability to fast is due to an unavoidable reason, such as illness, old age, or fear of worsening an illness, and not due to a matter of choice like travel or work, unless his work is essential for providing for his livelihood. The ruling regarding a man saying to his wife, "You are unlawful to me," has been previously detailed in earlier fatāwā, and it is preponderant that its ruling depends on the intention of the speaker.
