(2) CHAPTER. As-Salat (the prayers) at Mina (during Hajj).
Narrated `Abdullah bin `Umar: I offered the prayer with the Prophet, Abu Bakr and `Umar at Mina and it was of two rak`at. `Uthman in the early days of his caliphate did the same, but later on he started praying the full prayer.
Narrated Haritha bin Wahab: The Prophet I led us in the prayer at Mina during the peace period by offering two rak`at.
Narrated `Abdur Rahman bin Yazid: We offered a four rak`at prayer at Mina behind Ibn `Affan . `Abdullah bin Mas`ud was informed about it. He said sadly, Truly to Allah we belong and truly to Him we shall return. And added, I prayed two rak`at with Allah's Apostle at Mina and similarly with Abu Bakr and with `Umar (during their caliphates). He further said, May I be lucky enough to have two of the four rak`at accepted (by Allah).
