عَنْهُ عَنِ اَلْهَيْثَمِ بْنِ مَسْرُوقٍ اَلنَّهْدِيِّ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ قَالَ: دَخَلْتُ عَلَى أَبِي اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ وَ فِي مَنْزِلِهِ كَنِيفٌ مُسْتَقْبِلَ اَلْقِبْلَةِ سَمِعْتُهُ يَقُولُ« مَنْ بَالَ حِذَاءَ اَلْقِبْلَةِ ثُمَّ ذَكَرَ فَانْحَرَفَ عَنْهَا إِجْلاَلاً لِلْقِبْلَةِ وَ تَعْظِيماً لَهَا لَمْ يَقُمْ مِنْ مَقْعَدِهِ ذَلِكَ حَتَّى يَغْفِرَ اَللَّهُ لَهُ».
Narrated by al-Haytham ibn Masruq al-Nahdi, from Muhammad ibn Isma'il:
I entered upon Abu al-Hasan al-Ridha عليه السلام, and in his house, there was a lavatory facing the qiblah. I heard Imam عليه السلام say: "Whoever urinates while facing the qiblah, and then remembers and turns away from it out of reverence and respect for the qiblah, shall not leave that position until Allah سبحانه وتعالى forgives him."
