Abu Saeed Khudri reported,

The Messenger of Allah ﷺ used to go out on the day of Fitr and the day of Adha to the prayer ground. The first thing he would begin with was the prayer. Then he would turn and stand facing the people, while the people remained seated in their rows, and he would exhort them, advise them, and instruct them. If he wished to dispatch an expedition or order something, he would issue the command, and then he would depart.Abu Saeed said, "The people continued in that practice until I went out with Marwan, who was the governor of Madinah, on an Adha or Fitr day. When we reached the prayer ground, there was a pulpit that Kathir bin Salt had built, and Marwan intended to climb it before performing the prayer. So I tugged at his garment, but he pulled it away from me, ascended the pulpit, and delivered the sermon before the prayer."I said to him, "By Allah, you have changed it!"He replied, "Abu Saeed, what you know is gone."I said, "By Allah, what I know is better than what I do not know."He said, "The people no longer sit for us after the prayer, so I made it before the prayer."In another narration, he said, "The Messenger of Allah ﷺ used to go out on the day of Adha and the day of Fitr and begin with the prayer. When he had completed his prayer, he would stand and face the people while they remained seated in their place of prayer. If he had need to dispatch an expedition, he would mention it to the people, and if he had any other matter, he would instruct them concerning it. He used to say, 'Give in charity, give in charity, give in charity,' and the women were the most who gave. Then he would depart.The practice continued in this way until the time of Marwan bin Hakam. I went out accompanying Marwan until we reached the prayer ground, and there was Kathir bin Salt, who had built a pulpit of clay and bricks. Marwan was pulling his hand away from me as if drawing me toward the pulpit, while I was pulling him toward the prayer. When I saw that, I said, 'What about beginning with the prayer?'He said, 'No, Abu Saeed, what you know has been abandoned.'I said, 'Never! By the One in whose hand is my soul, you will not bring anything better than what I know,' three times. Then he departed."

عن أبي سعيد قال

كان رسول الله ﷺ يخرج يوم الفطر والأضحى إلى المصلى، وأول شيء يبدأ به الصلاة، ثم ينصرف فيقوم مقابل الناس- والناس جلوس على صفوفهم- فيعظهم ويوصيهم ويأمرهم، وإن كان يريد أن يقطع بعثا أو يأمر بشيء أمر به، ثم ينصرف، وقال أبو سعيد: فلم يزل الناس على ذلك، حتى خرجت مع مروان، وهو أمير المدينة في أضحى- أو فطر- فلما أتينا المصلى إذا منبر قد بناه كثير بن الصلت، فإذا هو يريد أن يرتقيه قبل أن يصلي، فجبذت بثوبه، فجبذني وارتفع، فخطب قبل الصلاة، فقلت له: غيرتم والله! فقال: أبا سعيد، ذهب ما تعلم فقلت: ما أعلم والله خير مما لا أعلم، فقال: إن الناس لم يكونوا يجلسون لنا بعد الصلاة، فجعلتها قبل الصلاة. وفي رواية قال: إن رسول الله ﷺ كان يخرج يوم الأضحى ويوم الفطر، فيبدأ بالصلاة، فإذا صلى صلاته قام فأقبل على الناس وهم جلوس في مصلاهم، فإن كانت له حاجة ببعث ذكره للناس، أو حاجة بغير ذلك أمرهم بها، وكان يقول: تصدقوا، تصدقوا، تصدقوا، فكان أكثر من يتصدق النساء، ثم انصرف، فلم يزل انصرف فلم يزل كذلك حتى كان مروان بن الحكم، فخرجت محاضرا مروان حتى أتينا المصلى، فإذا كثير بن الصلت قد بنى منبرا من طين ولبن، فإذا مروان ينازعني يده، كأنه يجرني نحو المنبر، وأنا أجره نحو الصلاة، فلما رأيت ذلك قلت: أين الابتداء بالصلاة؟ قال: لا يا أبا سعيد، قد ترك ما تعلم، قلت: كلا، والذي نفسي بيده لا تأتون بخير مما أعلم- ثلاث مرات- ثم انصرف.
