Why did Allah combine the four times in one time?
Machine translationRead the Arabic original
The questioner : Why did Allah combine these four times in one time?
The Shaykh :[Al-Isra 17:78].
The questioner : Because of the importance of the Fajr prayer.
The Shaykh : Peace. Extension.
The questioner : Because there is no interval between the times of these four prayers, whereas for Fajr there is an interval.
The Shaykh : Their times are continuous, from midday to midnight. After midnight, there is no time for 'Isha' or any other prayer. Fajr is independent; no prayer is connected to it before it, and no prayer is connected to it after it.
The Shaykh :
at the decline of the sun [from its meridian] until the darkness of the night
لِدُلُوكِ الشَّمْسِ إِلَىٰ غَسَقِ اللَّيْلِThe questioner : Because of the importance of the Fajr prayer.
The Shaykh : Peace. Extension.
The questioner : Because there is no interval between the times of these four prayers, whereas for Fajr there is an interval.
The Shaykh : Their times are continuous, from midday to midnight. After midnight, there is no time for 'Isha' or any other prayer. Fajr is independent; no prayer is connected to it before it, and no prayer is connected to it after it.
