It is preferable for the imam to ascend the pulpit immediately after the sun has passed its zenith

Your Eminence! When the imam ascends the pulpit, the second adhan is called, and the women pray upon this adhan. What if the adhan is called before the time of Dhuhr has entered? If the women pray, is their prayer invalid, or should they delay it?

First: The imam should not come except after the sun has passed its zenith, and he should not come before that; because this is the time agreed upon by the scholars.Some of the scholars say: If the imam preaches before the sun passes its zenith, it is not valid, so the agreed-upon time is after the sun has passed its zenith.It is said to the imam: It is preferable that he not come except immediately after the sun has passed its zenith. If he comes immediately after the sun has passed its zenith and the adhan is called, then the time of Dhuhr has entered, and the women pray Dhuhr in their homes. However, there is no harm in his coming an hour or so before the sun passes its zenith. If he does come, let there be news among the women and the sick in their homes that the imam is coming before the sun passes its zenith, so that they wait. And now, praise be to Allah, clocks are available.It is said to the women: Do not pray except in the time in which you used to pray on other days.
They should be informed of this.
