Question? What is your opinion when a man divorces his wife three times in clear, explicit words in one sitting?
A single divorce should be given as it is sufficient and it is the Islamic way. If for specific reasons, three divorces need to be given, the Sunnah (preferred) divorce is to pronounce three divorces in three separate intervals of menstruations (Tuhr), in which no sexual intercourse with the wife has taken place.
However, if a man divorces his wife three times (or more) using clear, explicit words in a single setting then according to the Hanafī school of Law his wife is irrevocably divorced from him.
