Fasting two consecutive months if one begins at the start of the lunar month

Question:
If he began his fasting from the first of Rabi' al-Awwal and fasted through Rabi' al-Thani until he saw the new moon, and the month was short, does this suffice for his expiation?

Answer:
If he begins fasting from the new moon, he builds upon it. But who sees the new moon? Today, one does not see the new moon, nor is it expected, for the new moon begins from the middle of the month. In any case, sixty days is more precise and better, because seeing the new moon requires specific criteria and requires delaying the fast until the new moon arrives. Yes.
