مُحَمَّدُ بْنُ أَحْمَدَ بْنِ يَحْيَى عَنْ إِبْرَاهِيمَ بْنِ هَاشِمٍ أَوْ غَيْرِهِ عَنْ صَفْوَانَ عَنْ أَبِي اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ:« نَهَى رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ أَنْ يُجِيبَ اَلرَّجُلُ آخَرَ وَ هُوَ عَلَى اَلْغَائِطِ أَوْ يُكَلِّمَهُ حَتَّى يَفْرُغَ».
Muhammad bin Ahmad bin Yahya narrated from Ibrahim bin Hashim or someone else, from Safwan, from Abu Al-Hasan Al-Ridha عليه السلام, who said:
Imam عليه السلام said: 'The Messenger of Allah سبحانه وتعالى (may Allah سبحانه وتعالى bless him and his family) forbade a man from responding to another person or speaking to him while relieving himself, until he has finished.'
