Narrated `Amr:I heard Abu Ash-sha'tha' Jabir saying, "I heard Ibn `Abbas saying, 'I offered with Allah's Messenger (ﷺ) eight rak`at (of Zuhr and `Asr prayers) together and seven rak`at (the Maghrib and the `Isha' prayers) together.' " I said, "O Abu Ash-shatha! I think he must have prayed the Zuhr late and the `Asr early; the `Isha early and the Maghrib late." Abu Ash-sha'tha' said, "I also think so." (See Hadith No. 518 Vol. 1).
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، قَالَ سَمِعْتُ أَبَا الشَّعْثَاءِ، جَابِرًا قَالَ سَمِعْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنه ـ قَالَ صَلَّيْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم ثَمَانِيًا جَمِيعًا وَسَبْعًا جَمِيعًا. قُلْتُ يَا أَبَا الشَّعْثَاءِ أَظُنُّهُ أَخَّرَ الظُّهْرَ وَعَجَّلَ الْعَصْرَ وَعَجَّلَ الْعِشَاءَ وَأَخَّرَ الْمَغْرِبَ. قَالَ وَأَنَا أَظُنُّهُ.
