Machine translationRead the Arabic original
The questioner : Is the adhan of the Sunnah for the time or for the prayer?
The Shaykh : The adhan for the Fajr prayer; it is recommended to advance it.
The questioner : No, no, my intention is: is the adhan made for the time or for the prayer?
The Shaykh : For the time, because it is the Sunnah for the Fajr prayer to advance it from the moment the time enters, so you leave a space for the regular voluntary prayer,
The questioner : in every prayer.
The Shaykh : In every time, because it follows the prayer, but what is prescribed is that the prayer be in the first part of the time, except for the late 'Isha' prayer and except for cooling off in the Zuhr prayer,
