حَدَّثَنَا مُعَاذٌ حَدَّثَنَا ابْنُ عَوْنٍ عَنْ مُحَمَّدٍ عَنِ ابْنِ عَبَّاسٍ قَالَ قَدْ سِرْنَا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَيْنَ مَكَّةَ وَالْمَدِينَةِ لَا نَخَافُ إِلَّا اللَّهَ عَزَّ وَجَلَّ نُصَلِّي رَكْعَتَيْنِ
مسند امام احمد بن حنبل · Hadith 3493
It was narrated that Ibn 'Abbas (RA) said: We travelled with the Messenger of Allah (PBUH) between Makkah and Madinah not fearing anyone but Allah, may He be glorified and exalted, and we prayed two rak'ahs [i.e., shortened the four rak'ah prayers].
