Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ مَنْصُورٍ عَنْ هِلَالِ بْنِ يَسَافٍ عَنْ أَبِي يَحْيَى الْأَعْرَجِ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ قَالَ سَأَلْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ صَلَاةِ الرَّجُلِ قَاعِدًا فَقَالَ عَلَى النِّصْفِ مِنْ صَلَاتِهِ قَائِمًا.
English Translation
Muhammad ibn Ja'far narrated to us: Shu'bah narrated from Mansur from Hilal ibn Yasaf from Abu Yahya al-A'raj from Abdullah ibn Amr ibn al-As who said: I asked the Messenger of Allah (peace be upon him) about the prayer of a person sitting. He said: "It is half the reward of the prayer of a person standing."
