Exact Fasting Protocol of Dawud (a.s)

Prophet Dawud's (AS) fasting is termed as Alternate Day fasting. I've been following daily fasts but now switching to Alternate Day Fasting Protocol since Muhammad SAW called it the best way (Reference ). The first day is clear, it's the second day which is confusing. Day 1 - Fast for 24 hours (No food, no water, clear) **Day 2 Questions** **Water**: I assume I can drink water throughout the day. **Frequency**: Eat 3 meals a day (breakfast, lunch, dinner) or one meal a day (aka **OMAD**) If Frequency is OMAD then options are Option A) Eat at the 01th hour Option B) Eat at sunset Option C) Eat at 23rd hour **I'm looking for the Precise Protocol followed by Prophet Dawud AS.**
