It was said to Salman: Your Prophet teaches you everything, even about excrement. He replied: Yes. He has forbidden us to face the qiblah at the time of easing or urinating, and cleansing with right hand, and cleansing with less than three stones, or cleansing with dung or bone. (Using translation from Abū Dāʾūd 7)   

قَالُوا لِسَلْمَانَ قَدْ عَلَّمَكُمْ نَبِيُّكُمْ ﷺ كُلَّ شَيْءٍ قَالَ «أَجَلْ قَدْ نَهَى رَسُولُ اللهِ ﷺ أَنْ نَسْتَقْبِلَ الْقِبْلَةَ بغائطٍ أَوْ بَوْلٍ وَأَنْ يَسْتَنْجِيَ أَحَدُنَا بِالْيَمِينِ أَوْ أَنْ يَسْتَنْجِيَ أَحَدُنَا بِأَقَلَّ مِنْ ثَلَاثَةِ أَحْجَارٍ وَأَنْ يَسْتَنْجِيَ بِرَجِيعٍ أَوْ عَظْمٍ»  

[Machine] We entered upon Salman and he brought us close to what was in the house, and he said, "If it were not for the fact that the Messenger of Allah ﷺ prohibited us, or if we were not prohibited from a man incurring a debt on behalf of his brother, I would have incurred debts for you."  

دَخَلْنَا عَلَى سَلْمَانَ فَقَرَّبَ إِلَيْنَا مَا كَانَ فِي الْبَيْتِ وَقَالَ «لَوْلَا أَنَّ رَسُولَ اللهِ ﷺ نَهَانَا أَوْ لَوْلَا نُهِينَا عَنْ أَنْ يَتَكَلَّفَ الرَّجُلُ لِأَخِيهِ لَتَكَلَّفْتُ لَكُمْ»  

[Machine] "The Messenger of Allah ﷺ prohibited us from burdening ourselves for a guest."  

«نَهَانَا رَسُولُ اللهِ ﷺ أَنَّ نَتَكَلَّفَ لِلضَّيْفِ»  

[Machine] I and my companion went to Salman Al-Farsi, and Salman said, "If the Messenger of Allah ﷺ had not prohibited us from unnecessary expenses, I would have incurred expenses for you, and then he brought bread and meat." My companion said, "If we had salt, you would have sent your flask to get it." Then Salman sent his utensil and pledged it, and then he brought salt. When we ate it, my companion said, "Praise be to Allah who has blessed us with what He has provided us." Salman said, "If you were content with what Allah has provided you, my utensil would not have been pledged."  

ذَهَبْتُ أَنَا وَصَاحِبٌ لِي إِلَى سَلْمَانَ الْفَارِسِيِّ فَقَالَ سَلْمَانُ «لَوْلَا أَنَّ رَسُولَ اللهِ ﷺ نَهَانَا عَنِ التَّكَلُّفِ لَتَكَلَّفْتُ لَكَ ثُمَّ جَاءَ بِخُبْزٍ وَلَحْمٍ» فَقَالَ صَاحِبِي لَوْ كَانَ فِي مِلْحِنَا صَعْتَرٌ فَبَعَثَ سَلْمَانُ بِمَطْهَرَتِهِ فَرَهَنَهَا ثُمَّ جَاءَ بِصَعْتَرٍ فَلَمَّا أَكَلْنَاهُ قَالَ صَاحِبِي الْحَمْدُ لِلَّهِ الَّذِي مَتَّعَنَا بِمَا رَزَقَنَا فَقَالَ سَلْمَانُ ؓ «لَوْ قَنَعْتَ بِمَا رَزَقَكَ اللهُ لَمْ تَكُنْ مَطْهَرَتِي مَرْهُونَةً»
