When does the time for the Zuhr prayer begin for women on Friday, is it after the first adhan or the second?

Question:
May Allah reward you. In his other question, he says: If the mu'adhdhin gives the first adhan on Friday after the sun has passed its zenith, are women required to wait until the second adhan and then pray, or what is required of them?

Answer:
When the sun passes its zenith, the time for Zuhr begins. Whoever prays after the sun has passed its zenith has performed the prayer in its time, whether the mu'adhdhin gives the adhan or not. The important thing is the passing of the sun; when that happens, the time for Zuhr begins. At that point, whoever prays after the sun has passed its zenith has performed the prayer in its time. And whoever prays before the sun passes its zenith, it does not suffice for him, because he prayed before the time. So when the sun passes its zenith, women pray Zuhr, whether the men pray Jumu'ah or not. And if they do not know that the sun has passed its zenith, the adhan is sufficient for them, because the adhan is a sign of the sun passing its zenith.
