Ibn 'Abbas reported:

I observed with the Messenger of Allah (ﷺ) eight (rak'ahs) in combination, and seven rak'ahs in combination. I (one of the narrators) said: O Abd Sha'tha', I think that he (the Prophet) had delayed the noon prayer and hastened the afternoon prayer, and he delayed the sunset prayer and hastened the 'Isha' prayer. He said: I also think so.

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عَمْرٍو، عَنْ جَابِرِ بْنِ زَيْدٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ صَلَّيْتُ مَعَ النَّبِيِّ صلى الله عليه وسلم ثَمَانِيًا جَمِيعًا وَسَبْعًا جَمِيعًا ‏.‏ قُلْتُ يَا أَبَا الشَّعْثَاءِ أَظُنُّهُ أَخَّرَ الظُّهْرَ وَعَجَّلَ الْعَصْرَ وَأَخَّرَ الْمَغْرِبَ وَعَجَّلَ الْعِشَاءَ ‏.‏ قَالَ وَأَنَا أَظُنُّ ذَاكَ ‏.‏
