Sahih Muslim Introduction 77
Hasan al-Hulwānī narrated to us, he said, I heard Shabābah say:
‘Abd ul-Quddūs was narrating to us saying,‘Suwayd bin Aqalah said…’ [when it should be ‘bin Ghafalah’] Shabābah said: ‘And I heard Abd ul-Quddūs saying, ‘The Messenger of Allah, peace and blessings of Allah upon him, prohibited taking a Rawḥ by accident’. [Shabābah] said: ‘So it was said to him, ‘What does this mean?’ [Abd ul-Quddūs] said: ‘It means to make an opening in a wall [thus letting] a breeze enter [by accident]’.’ [He changed the original Ḥadīth, switching ‘Rūḥ’ meaning ‘soul’ to ‘Rawḥ’ or ‘breeze’, and he switched ‘Gharaḍān’ meaning ‘as a target’ to ‘Arḍān’ or ‘accidentally’. All simply by changing a few letters in the words] Muslim said, I heard Ubayd Allah bin Umar al-Qawārīrī saying, I heard Hammād bin Zayd saying to a man after he sat with Mahdī bin Hilāl for days: ‘What is this salty well [i.e. useless or harmful] which has sprung up in your direction?’ He said: ‘Yes, oh Abā Ismā’īl [in agreement]’.
حَدَّثَنَا حَسَنٌ الْحُلْوَانِيُّ، قَالَ سَمِعْتُ شَبَابَةَ، قَالَ كَانَ عَبْدُ الْقُدُّوسِ يُحَدِّثُنَا فَيَقُولُ سُوَيْدُ بْنُ عَقَلَةَ ‏.‏ قَالَ شَبَابَةُ وَسَمِعْتُ عَبْدَ الْقُدُّوسِ يَقُولُ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم أَنَّ يُتَّخَذَ الرَّوْحُ عَرْضًا ‏.‏ قَالَ فَقِيلَ لَهُ أَىُّ شَىْءٍ هَذَا قَالَ يَعْنِي تُتَّخَذُ كُوَّةٌ فِي حَائِطٍ لِيَدْخُلَ عَلَيْهِ الرَّوْحُ ‏.‏ 
قَالَ مُسْلِمٌ وَسَمِعْتُ عُبَيْدَ اللَّهِ بْنَ عُمَرَ الْقَوَارِيرِيَّ، يَقُولُ سَمِعْتُ حَمَّادَ بْنَ زَيْدٍ، يَقُولُ لِرَجُلٍ بَعْدَ مَا جَلَسَ مَهْدِيُّ بْنُ هِلاَلٍ بِأَيَّامٍ مَا هَذِهِ الْعَيْنُ الْمَالِحَةُ الَّتِي نَبَعَتْ قِبَلَكُمْ قَالَ نَعَمْ يَا أَبَا إِسْمَاعِيلَ ‏.‏
