Arabic (Original)
حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ عَنْ مَالِكٍ عَنْ أَبِي حَازِمٍ عَنْ سَهْلِ بْنِ سَعْدٍ قَالَ كَانَ النَّاسُ يُؤْمَرُونَ أَنْ يَضَعُوا الْيُمْنَى عَلَى الْيُسْرَى فِي الصَّلَاةِ قَالَ أَبُو حَازِمٍ وَلَا أَعْلَمُ إِلَّا يُنْمِي ذَلِكَ قَالَ أَبُو عَبْد الرَّحْمَنِ يُنْمِي يَرْفَعُهُ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ.
English Translation
Abd al-Rahman ibn Mahdi narrated to us, from Malik, from Abu Hazim, from Sahl ibn Sa'd, who said: The people used to be commanded to place their right hand over their left in prayer. Abu Hazim said: I do not know it except as something traced back to the Prophet. Abu Abd al-Rahman said: this means it is attributed to the Prophet, peace and blessings be upon him.
