٧ـ عَنْهُ عَنْ يَحْيَى بْنِ إِبْرَاهِيمَ بْنِ أَبِي الْبِلادِ السُّلَمِيِّ عَنْ أَبِيهِ عَنْ جَدِّهِ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ لَوْ عَلِمَ الله شَيْئاً أَدْنَى مِنْ أُفٍّ لَنَهَى عَنْهُ وَهُوَ مِنْ أَدْنَى الْعُقُوقِ وَمِنَ الْعُقُوقِ أَنْ يَنْظُرَ الرَّجُلُ إِلَى وَالِدَيْهِ فَيُحِدَّ النَّظَرَ إِلَيْهِمَا.
7. It is narrated from him (narrator of the Hadith above) from Yahya ibn Ibrahim ibn abu al-Balad al-Sullami from his father from his grand father from Abu ‘Abdillah  who has said the following: “Had Allah known anything expressing a lesser degree of disappointment than ‘Uff, He would have prohibited to use it against parents. Using the expression ‘Uff is the minimum form of causing suffering and disappointment to parents. Of the cases of causing suffering and disappointment to parents is one’s look and staring at them.”
