‘Abd Allah b. Buraidah said :‘Imran b. Hussain asked the prophet (ﷺ) about the prayer a man offers in sitting condition. He replied: his prayer in standing condition is better than his prayer in sitting condition, and his prayer in sitting condition is half the prayer he offers in standing condition, and his prayer in lying condition is half the prayer he offers in sitting condition.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ حُسَيْنٍ الْمُعَلِّمِ، عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، أَنَّهُ سَأَلَ النَّبِيَّ صلى الله عليه وسلم عَنْ صَلاَةِ الرَّجُلِ قَاعِدًا فَقَالَ " صَلاَتُهُ قَائِمًا أَفْضَلُ مِنْ صَلاَتِهِ قَاعِدًا وَصَلاَتُهُ قَاعِدًا عَلَى النِّصْفِ مِنْ صَلاَتِهِ قَائِمًا وَصَلاَتُهُ نَائِمًا عَلَى النِّصْفِ مِنْ صَلاَتِهِ قَاعِدًا " .
