Al-'Abbas sought permission from the Messenger of Allah (ﷺ) to pass the night at Mecca during the period of his stay at Mina for distributing water among the people. He gave him permission.
Sunan Abi Dawud Book 11, Hadith 239
← Previous Hadith We sell the property of the people; so one of us goes to Mecca and passes the night there with the property (during the stay at Mina). He said: The Messenger of Allah (ﷺ) used to pass night and day at Mina.

Sunan Abi Dawud Book 11, Hadith 238 Next Hadith → 'Uthman prayed four rak'ahs at Mina. 'Abd Allah (b. Mas'ud) said: I prayed two rak'ahs along with the Prophet (ﷺ) and two rak'ahs along with 'Umar. The version of Hafs added: And along with 'Uthman during the early period of his caliphate. He ('Uthman) began to offer complete prayer (i.e. four rak'ahs) later on. The version of Abu Mu'awiyah added: Then your modes of action varied. I would like to pray two rak'ahs acceptable to Allah instead of four rak'ahs.

Al-A'mash said: Mu'awiyah b. Qurrah reported to me from his teachers: 'Abd Allah (b. Mas'ud) once prayed four rak'ahs. He was told: You criticized 'Uthman but you yourself prayed four ? He replied: Dissension is evil.
