"I accompanied the Messenger of Allah on eighteen journeys, and I did not see him leave the two Rak'ah when the sun waned before Zuhr."  

صَحِبْتُ رَسُولَ اللَّهِ ﷺ ثَمَانِيَةَ عَشَرَ سَفَرًا فَمَا رَأَيْتُهُ تَرَكَ الرَّكْعَتَيْنِ إِذَا زَاغَتِ الشَّمْسُ قَبْلَ الظُّهْرِ وَفِي الْبَابِ عَنِ ابْنِ عُمَرَ  

"I prayed Zuhr with the Prophet on a journey as two Rak'ah, and two Rak'ah after it."  

صَلَّيْتُ مَعَ النَّبِيِّ ﷺ الظُّهْرَ فِي السَّفَرِ رَكْعَتَيْنِ وَبَعْدَهَا رَكْعَتَيْنِ  

"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."  

صَلَّيْتُ مَعَ النَّبِيِّ ﷺ فِي الْحَضَرِ وَالسَّفَرِ فَصَلَّيْتُ مَعَهُ فِي الْحَضَرِ الظُّهْرَ أَرْبَعًا وَبَعْدَهَا رَكْعَتَيْنِ وَصَلَّيْتُ مَعَهُ فِي السَّفَرِ الظُّهْرَ رَكْعَتَيْنِ وَبَعْدَهَا رَكْعَتَيْنِ وَالْعَصْرَ رَكْعَتَيْنِ وَلَمْ يُصَلِّ بَعْدَهَا شَيْئًا وَالْمَغْرِبَ فِي الْحَضَرِ وَالسَّفَرِ سَوَاءً ثَلاَثَ رَكَعَاتٍ لاَ تَنْقُصُ فِي الْحَضَرِ وَلاَ فِي السَّفَرِ وَهِيَ وِتْرُ النَّهَارِ وَبَعْدَهَا رَكْعَتَيْنِ
