Hadith 1415
Chapter 32: How Many Khutbahs Should Be Delivered? - كتاب الجمعة
أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ حَدَّثَنَا شَرِيكٌ، عَنْ سِمَاكٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ جَالَسْتُ النَّبِيَّ صلى الله عليه وسلم فَمَا رَأَيْتُهُ يَخْطُبُ إِلاَّ قَائِمًا وَيَجْلِسُ ثُمَّ يَقُومُ فَيَخْطُبُ الْخُطْبَةَ الآخِرَةَ .
It was narrated that Jabir bin Samurah said:
"I sat with the Prophet (ﷺ) and I did not see him deliver the khutbah except standing, and he sat, then he stood up and delivered the second khutbah."
