5. Establishing the Prayer and the Sunnah Regarding Them - كتاب إقامة الصلاة والسنة فيها
It was
narrated from ‘Imran bin Husain that he asked the Messenger of
Allah (ﷺ) about a man who prays sitting down. He said, “Whoever
performs prayer standing up, that is better. Whoever performs prayer
sitting down will have half the reward of one who prays standing. And
whoever performs prayer lying down will have half the reward of one
who prays sitting.”
حَدَّثَنَا بِشْرُ بْنُ هِلاَلٍ الصَّوَّافُ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ حُسَيْنٍ الْمُعَلِّمِ، عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، أَنَّهُ سَأَلَ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ عَنِ الرَّجُلِ يُصَلِّي قَاعِدًا قَالَ . " مَنْ صَلَّى قَائِمًا فَهُوَ أَفْضَلُ وَمَنْ صَلَّى قَاعِدًا فَلَهُ نِصْفُ أَجْرِ الْقَائِمِ وَمَنْ صَلَّى نَائِمًا فَلَهُ نِصْفُ أَجْرِ الْقَاعِدِ "
