١٠ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ الله رَفَعَهُ قَالَ قِيلَ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) يَزْعُمُ بَعْضُ النَّاسِ أَنَّ النُّورَةَ يَوْمَ الْجُمُعَةِ مَكْرُوهَةٌ فَقَالَ لَيْسَ حَيْثُ ذَهَبَ أَيُّ طَهُورٍ أَطْهَرُ مِنَ النُّورَةِ يَوْمَ الْجُمُعَةِ. 
10. Ali ibn Ibrahim has narrated from Ahmad ibn abu ‘Abd Allah in a marfu‘ manner saying: “Someone said to abu ‘Abd Allah , ‘Certain people consider applying Nurah (lime as hair cleaner) on Friday as undesirable.’ The Imam said, ‘It is not as they say. No other cleaner is a better cleaner on Friday than Nurah.’” (The following chapters are best explained by fatwa.)
