Salim bin 'Abdullah (b. 'Umar) reported on the authority of his father that Allah's Messenger ( صلی اللہ علیہ وسلم ) observed the prayer of a traveller, i. e. two rak'ahs in Mina, and other places; so did Abu Bakr (RA) and 'Umar, and 'Uthman too observed two rak'ahs at the beginning of his caliphate, but he then completed four.

A hadith like this has been reported by Zuhri, with the same chain of transmitters, and in it mention was made of Mina only, but not of other places.

Ibn 'Umar reported: The Messenger of Allah ( صلی اللہ علیہ وسلم ) said two rak'ahs at Mina, and Abu Bakr (RA) after him, and 'Umar after Abu Bakr, and 'Uthman at the beginning of his caliphate; then 'Uthman observed four rak'ahs, and when Ibn 'Umar prayed with the Imam, he said four rak'ahs, but when he observed prayer alone, he said two rak'ahs.

A hadith like this has been narrated by the same chain of transmitters.

Ibn 'Umar reported: The Apostle of Allah ( صلی اللہ علیہ وسلم ) said in Mina the prayer of a traveller (short prayer) ; Abu Bakr (RA) and 'Umar did the same and 'Uthman did it for eight years or six years. Hafs (one of the narrators) said: Ibn 'Umar would also say two rak'ahs at Mina and then go to bed. I said to him: O uncle, I wish you could have said two rak'ahs (of Sunnah prayer after shortening the Fard prayer). He said: Were I to do that, I would have completed the prayer.

This hadith has been narrated by Shu'bah with the same chain of transmitters but no mention has been made of Mina, but they (the narrators) only said: He prayed while travelling.

Ibrahim reported: I heard 'Abdul Rahman as saying; 'Uthman led us four rak'ahs of prayer at Mina. It was reported to 'Abdullah bin Mas'ud and he recited: "Surely we are Allah's and to Him shall we return," and then said: I prayed with the Messenger of Allah ( صلی اللہ علیہ وسلم ) at Mina two rak'ahs of prayer. I prayed along with Abu Bakr (RA) al-Siddiq two rak'ahs of prayer at Mina. I prayed along with 'Umar bin Khattab two rak'ahs of prayer at Mina. I wish I had my share of the two rak'ahs acceptable (to God) for the four rak'ahs.

A hadith like this has been reported by A'mash with the same chain of transmitters.

Haritha bin Wahb reported: I prayed with the Messenger of Allah ( صلی اللہ علیہ وسلم ) two rak'abs and most of them offered two rak'ahs only in Mina, while the people felt secure.

Wahb al-Khuza'i reported: I prayed behind the Messenger of Allah ( صلی اللہ علیہ وسلم ) at Mina, and there was the greatest number of people, and they prayed two rak'ahs on the occasion of the Farwell Pilgrmage. (Muslim said: Haritha bin Wahb al-Khuza'i is the brother of 'Ubaidullah bin 'Umar son of Khattab from the side of mother.)
