Hadith.4772 - Ṣafwan ibn Yaḥya narrated from Abu Khalid al-Qammaṭ, who said: I said to Abu Abdillah (as): "A man who sometimes understands his own position and at other times denies it, can his guardian (wali) issue a divorce on his behalf?" Imam (as) said: "What is wrong with him? Can he not divorce himself?" I said: "He does not understand the rules of divorce, and if he divorces today, he might say tomorrow that he did not divorce."
