Sahih Muslim Book 6, Hadith 22
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.
Salim b. 'Abdullah (b. 'Umar) reported on the authority of his father that Allah's Messenger (ﷺ) observed the prayer of a traveller, i. e. two rak'ahs in Mina, and other places; so did Abu Bakr and 'Umar, and 'Uthman too observed two rak'ahs at the beginning of his caliphate, but he then completed four.
The Messenger of Allah (ﷺ) said two rak'ahs at Mina, and Abu Bakr 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.
