حَدَّثَنَا عَبْدُ الرَّزَّاقِ حَدَّثَنَا سُفْيَانُ عَنْ أَبِي الزُّبَيْرِ عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنِ ابْنِ عَبَّاسٍ قَالَ جَمَعَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَيْنَ الظُّهْرِ وَالْعَصْرِ بِالْمَدِينَةِ فِي غَيْرِ سَفَرٍ وَلَا خَوْفٍ قَالَ قُلْتُ يَا أَبَا الْعَبَّاسِ وَلِمَ فَعَلَ ذَلِكَ قَالَ أَرَادَ أَنْ لَا يُحْرِجَ أَحَدًا مِنْ أُمَّتِهِ
مسند امام احمد بن حنبل · Hadith 2557
It was narrated that Ibn 'Abbas (RA) said: The Prophet (PBUH) put Zuhr and 'Asr together in Madinah, when he was not travelling and there was no fear. I [the narrator] said: O Abul-' Abbas, why did he do that? He said: He did not want to make things difficult for anyone of his ummah.
