حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ الْفَزَارِيُّ حَدَّثَنَا حُمَيْدُ بْنُ عَلِيٍّ الْعُقَيْلِيُّ حَدَّثَنَا الضَّحَّاكُ بْنُ مُزَاحِمٍ عَنِ ابْنِ عَبَّاسٍ قَالَ صَلَّى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حِينَ سَافَرَ رَكْعَتَيْنِ وَحِينَ أَقَامَ أَرْبَعًا قَالَ قَالَ ابْنُ عَبَّاسٍ فَمَنْ صَلَّى فِي السَّفَرِ أَرْبَعًا كَمَنْ صَلَّى فِي الْحَضَرِ رَكْعَتَيْنِ قَالَ وَقَالَ ابْنُ عَبَّاسٍ لَمْ تُقْصَرْ الصَّلَاةُ إِلَّا مَرَّةً حَيْثُ صَلَّى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَكْعَتَيْنِ وَصَلَّى النَّاسُ رَكْعَةً رَكْعَةً
مسند امام احمد بن حنبل · Hadith 2262
It was narrated that Ibn 'Abbas (RA) said: The Messenger of Allah (PBUH) prayed two rak'ahs when travelling and four rak'ahs when not travelling. Ibn 'Abbas (RA) said: Whoever prays four rak'ahs when travelling is like the one who prays two rak'ahs when not travelling. Ibn 'Abbas (RA) said: Prayer was not shortened except once, when the Messenger of Allah (PBUH) prayed two rak'ahs , and the people prayed one rak'ah each [in two groups, as in the fear prayer].
