Abu An-Nadrah said: Imran bin Husain was asked about the traveler's prayer. He said: 'I performed Hajj with the Messenger of Allah, and he prayed two Rak'ah.

Anas bin Malik narrated: We prayed Zuhr as four with the Prophet in Al-Madinah, and Asr as two Rak'ah in Dhil-Hulaifah.

Yahya bin Abi Ishaq Al-Hadrami narrated : that Anas bin Malik said: We went with the Messenger of Allah from Al-Madinah to Makkah, and he prayed two Rak'ah. He said: I said to Anas: 'How long did Messenger of Allah stay in Makkah?' He said: 'Ten (days).'

Ibn Abbas narrated: The Messenger of Allah traveled on a journey and he prayed two Rak'ah for nineteen days. Ibn Abbas said: So when we would stay somewhere for nineteen (days) we would pray two Rak'ah , and if we stayed longer than that we would complete the Salat.

Ibn Umar narrated: I prayed with the Prophet both, while a resident and while traveling. So I prayed four for Zuhr with him as a resident, and two Rak'ah after it. I prayed two Rak'ah for Zuhr with him while traveling and two Rak'ah after it, and two Rak'ah for Asr, and he did not pray anything after it. Maghrib while a resident and traveling is the same; three Rak'ah, it is not decreased as a resident nor while traveling. It is Witr of the day, and after it are two Rak'ah.

Mu'adh bin Jabal narrated: While the Prophet as at the Battle of Tabuk, if he wanted to depart before the sun's decline he would delay Zuhr so that he could pray it together with Asr. If he wanted to depart after the sun's decline, he would hasten Asr to Zuhr, and pray Zuhr and Asr together, and then move it. If he wanted to depart before Maghrib he would delay Maghrib until he prayed it with Isha, and if he wanted to depart after Maghrib he would hasten Isha so that he would pray it along with Maghrib.
