Question
Why do we pray the Sunnah of Dhuhr as four units with one greeting and not as two units with two greetings? Is the Muslim given a choice in this matter?
Answer
I say, and with God's success: The issue is a matter of disagreement. According to Abu Hanifa, it is prayed four times with one salutation; because it is more consistent with the opening takbir, and God knows best.
