Whoever did not offer the Salat after the compulsory (congregational) Salat (prayers
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.
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).
