The ruling on the difference among mu'adhdhins regarding the time for the iqamah of the Fajr prayer

Question:
This questioner, Abu 'Abd al-'Aziz, says: I see a difference among the imams regarding the Fajr prayer. Some of them give the iqamah after one-third of an hour, while others wait until forty minutes or more. What is the guidance of the Prophet (peace and blessings be upon him) in this matter?

Answer:
It is better to hasten the Fajr prayer and other prayers by performing them at the beginning of their time, unless one is considering the delay of the congregation and waits for them as they arrive one after another; in that case, there is no harm. One should make the interval between the iqamah and the adhan, and between the adhan and the iqamah, the length of one-third of an hour or up to half an hour. This is the standard, and most people follow it. Yes.
