Salim narrated from his father (Sayyiduna Abdullah bin Umar, may Allah be pleased with them both) that I prayed with the Messenger of Allah (peace be upon him), Abu Bakr, and Umar (may Allah be pleased with them both) at Mina (the Zuhr and Asr prayers shortened) two rak‘ahs each. I also prayed two rak‘ahs with Sayyiduna Uthman (may Allah be pleased with him) at the beginning of his caliphate, but later he started offering the full prayer.

Brief Explanation
(Commentary on Hadith 1544)
In Mina, performing the four-unit (ruba‘i) prayer as two units (qasr) is correct, and many of the Companions (Sahabah) objected to this action of Sayyiduna ‘Uthman radi Allahu anhu. Several reasons have been mentioned for his completion (itmam) of the prayer. See: [شرح بخاري مولانا راز رحمه الله 1655].
