Narrated by:Jabir bin Samurah said
It was narrated that Jabir bin Samurah said:"I saw the Messenger of Allah (ﷺ) delivering the Khutbah standing up, then he sat down for a while and did not speak, then he stood up and delivered another Khutbah. Whoever tells you that the Prophet (ﷺ) delivered a Khutbah sitting do not believe him."
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ سِمَاكٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَخْطُبُ قَائِمًا ثُمَّ يَقْعُدُ قَعْدَةً لاَ يَتَكَلَّمُ فِيهَا ثُمَّ قَامَ فَخَطَبَ خُطْبَةً أُخْرَى فَمَنْ خَبَّرَكَ أَنَّ النَّبِيَّ صلى الله عليه وسلم خَطَبَ قَاعِدًا فَلاَ تُصَدِّقْهُ .
