Is the husband's saying, "I don't want you, go," followed by his saying over the phone, "Yes, that's what it is," when his wife asked him if this was a divorce, considered a divorce (talaq)? And is the word "Raddadtuk" (I have taken you back) over the phone sufficient to take the wife back?

The husband's saying to his wife, "I don't want you; go," is a metaphorical divorce (kinayah), and its occurrence depends on the husband's intention. His answer, "Yes, it is so," to her question, "Should I consider this a divorce?" confirms his intention to divorce. His statement, "I have taken you back," is considered a valid return (raj'ah) if this was not the third divorce and the waiting period (iddah (definition)) has not expired. Otherwise, there is no return except with a new contract. The spouses are advised to avoid marital disputes and divorce pronouncements.
