وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ ذَلِكَ قَدْ فَعَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَصَرَ الصَّلَاةَ وَأَتَمَّ. رَوَاهُ فِي شرح السّنة

Ibn ‘Umar said, “When travelling I prayed along with the Prophet two rak'as at the noon prayer and two after it.” In a version he said, “I prayed with the Prophet both when resident and when travelling. When resident I prayed along with him four rak'as at the noon prayer and two after it, and when travelling two at it and two after it; two rak'as at the afternoon prayer after which he prayed no more; and both when resident and travelling alike three rak'as at the sunset prayer, in which he never prayed less whether resident or travelling, this being the witr of the daytime. After it he prayed two rak'as.” Tirmidhi transmitted it.
