Machine translationRead the Arabic original
The Shaykh : It was part of the guidance of the Messenger (peace and blessings be upon him), and it was part of the guidance of the Prophet (peace and blessings be upon him) and the guidance of Abu Bakr, 'Umar, and 'Uthman in the early part of his caliphate, that people in Mina would shorten the prayer during Hajj. The meaning of shortening the prayer is: they pray Zuhr, 'Asr, and Maghrib with two rak'ahs.
The students: 'Isha'.
The Shaykh : Is that a mistake? They pray Zuhr, 'Asr, and 'Isha with two rak'ahs, and this continued for eight years during the time of 'Uthman, and he would pray the four-rak'ah prayers with two rak'ahs. How long did his caliphate last?
The student: ... .
The Shaykh : Yes, twelve years.
The students: 'Isha'.
