حَدَّثَنَا يَحْيَى عَنْ شُعْبَةَ حَدَّثَنَا قَتَادَةُ قَالَ سَمِعْتُ جَابِرَ بْنَ زَيْدٍ عَنِ ابْنِ عَبَّاسٍ قَالَ جَمَعَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَيْنَ الظُّهْرِ وَالْعَصْرِ وَالْمَغْرِبِ وَالْعِشَاءِ بِالْمَدِينَةِ فِي غَيْرِ خَوْفٍ وَلَا مَطَرٍ قِيلَ لِابْنِ عَبَّاسٍ وَمَا أَرَادَ إِلَى ذَلِكَ قَالَ أَرَادَ أَنْ لَا يُحْرِجَ أُمَّتَهُ
مسند امام احمد بن حنبل · Hadith 1953
It was narrated that Ibn 'Abbas said: The Messenger of Allah (PBUH) put Zuhr and ' Asr , and Maghrib and 'Isha’, together in Madinah when there was no state of fear or rain. It was said to Ibn 'Abbas: What was the purpose of that? He said: He did not want to cause any hardship for his ummah.
