Sahih Muslim Book 6, Hadith 24
A hadith like this has been narrated by the same chain of transmitters.
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.
The Apostle of Allah (ﷺ) said in Mina the prayer of a traveller (short prayer) ; Abu Bakr and 'Umar did the same and 'Uthmia 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 shorenting the Fard prayer). He said: Were I to do that, I would have completed the prayer.
