ذِكْرُ الْعِلَّةِ الَّتِي مِنْ أَجْلِهَا كَانَ يُصَلِّي الْمُصْطَفَى ﷺ جَالِسًا
[Machine] The Prophet ﷺ used to pray while sitting after he reached old age. When there were 30 verses remaining from the surah, he would stand up and recite them, then he would perform the rukoo' (bowing).
«كَانَ النَّبِيُّ ﷺ يُصَلِّي وَهُوَ جَالِسٌ بَعْدَمَا دَخَلَ فِي السِّنِّ وَكَانَ إِذَا بَقِيَ عَلَيْهِ مِنَ السُّورَةِ ثَلَاثُونَ آيَةً قَامَ فَقَرَأَهَا ثُمَّ رَكَعَ»
