[Machine] "I witnessed Uthman delivering a sermon while standing on the pulpit, and I witnessed Muawiya delivering a sermon while sitting. He said, 'Indeed, I am not ignorant of the Sunnah, but my age has advanced, my bones have weakened, and my needs have multiplied. So, I wanted to fulfill some of your needs while I am sitting, and then I will stand and take my share of the Sunnah.'"  

الطبراني:١٦٨٤٩حَدَّثَنَا عَبْدُ اللهِ بْنُ مُحَمَّدِ بْنِ الْعَبَّاسِ الْأَصْبَهَانِيُّ ثنا سَهْلُ بْنُ عُثْمَانَ ثنا يَحْيَى بْنُ زَكَرِيَّا بْنِ أَبِي زَائِدَةَ ثنا قَيْسُ بْنُ الرَّبِيعِ عَنْ مَيْسَرَةَ بْنِ حَبِيبٍ عَنْ مُوسَى بْنِ طَلْحَةَ قَالَ

شَهِدْتُ عُثْمَانَ يَخْطُبُ عَلَى الْمِنْبَرِ قَائِمًا وَشَهِدْتُ مُعَاوِيَةَ يَخْطُبُ قَاعِدًا فَقَالَ «أَمَا إِنِّي لَمْ أَجْهَلِ السُّنَّةَ وَلَكِنِّي كَبِرَتْ سِنِّي وَرَقَّ عَظْمِي وَكَثُرَتْ حَوَائِجُكُمْ فَأَرَدْتُ أَنْ أَقْضِيَ بَعْضَ حَوَائِجِكُمْ وَأَنَا قَاعِدٌ ثُمَّ أَقُومَ فَآخُذَ نَصِيبِي مِنَ السُّنَّةِ»
