Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ حَدَّثَنَا هِشَامٌ يَعْنِي ابْنَ سَعْدٍ عَنْ نَافِعٍ عَنْ ابْنِ عُمَرَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَى رَجُلًا سَاقِطًا يَدَهُ فِي الصَّلَاةِ فَقَالَ لَا تَجْلِسْ هَكَذَا إِنَّمَا هَذِهِ جِلْسَةُ الَّذِينَ يُعَذَّبُونَ.
English Translation
Muhammad b. Abdullah b. al-Zubayr told us, Hisham - meaning Ibn Sa'd - told us, from Nafi', from Ibn Umar, that the Messenger of Allah, peace and blessings be upon him, saw a man letting his hand droop during the prayer, and he said: "Do not sit like this; this is the sitting posture of those who are punished."
