Speaking after the Iqamah for Prayer
Question:
What is the ruling on speaking about matters outside the prayer, such as straightening the rows or other things, after the Iqamah for prayer has been called and before the opening Takbir, or speaking about worldly matters?
Answer:
Speaking about matters related to the prayer after the Iqamah and before the opening Takbir, such as straightening the ranks or other such things, is prescribed by Islamic law, but if it is not related to the prayer, then it is better to avoid it, in order to be prepared for entering the prayer and out of respect for it.
