A man should not call his father by his name nor sit down before

Al-Adab Al-Mufrad · Book 1 · Hadith 44

حَدَّثَنَا أَبُو الرَّبِيعِ، عَنْ إِسْمَاعِيلَ بْنِ زَكَرِيَّا، قَالَ‏:‏ حَدَّثَنَا هِشَامُ بْنُ عُرْوَةَ، عَنْ أَبِيهِ ‏,‏ أَوْ غَيْرِهِ أَنَّ أَبَا هُرَيْرَةَ أَبْصَرَ رَجُلَيْنِ، فَقَالَ لأَحَدِهِمَا‏:‏ مَا هَذَا مِنْكَ‏؟‏ فَقَالَ‏:‏ أَبِي، فَقَالَ‏:‏ لاَ تُسَمِّهِ بِاسْمِهِ، وَلاَ تَمْشِ أَمَامَهُ، وَلا تَجْلِسْ قَبْلَهُ‏.‏

Abu Hurayra saw two men and said to one of them, "Who is this man in relation to you?" He is my father," he replied. He said, "Do not call him by his own name nor walk in front of him nor sit down before him."
