Musnad Ahmad 80
It was narrated that Qais bin Abi Hazim said:
I was sitting with Abu Bakr as-Siddeeq, the successor of the Messenger of Allah (ﷺ), one month after the death of the Prophet (ﷺ) and he was telling a story, then the call went out among the people, `As-salatu jami'ah (prayer is about to begin),` and it was the first time that this call of `as-salatu jami'ah` went out to the people. The people gathered and he ascended the minbar, which was something that was made for him to deliver speeches, and it was the first speech he gave in Islam. He praised and glorified Allah, then he said: O People, I wish that someone else could have taken care of this for me, for if you compare my way to the way of your Prophet (ﷺ), I cannot be like him, for he was protected from the shaitan and the revelation used to come to him from heaven.
حَدَّثَنَا هَاشِمُ بْنُ الْقَاسِمِ، قَالَ حَدَّثَنَا عِيسَى يَعْنِي ابْنَ الْمُسَيَّبِ، عَنْ قَيْسِ بْنِ أَبِي حَازِمٍ، قَالَ إِنِّي لَجَالِسٌ عِنْدَ أَبِي بَكْرٍ الصِّدِّيقِ رَضِيَ اللَّهُ عَنْهُ خَلِيفَةِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَعْدَ وَفَاةِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِشَهْرٍ فَذَكَرَ قِصَّةً فَنُودِيَ فِي النَّاسِ أَنَّ الصَّلَاةَ جَامِعَةٌ وَهِيَ أَوَّلُ صَلَاةٍ فِي الْمُسْلِمِينَ نُودِيَ بِهَا إِنَّ الصَّلَاةَ جَامِعَةٌ فَاجْتَمَعَ النَّاسُ فَصَعِدَ الْمِنْبَرَ شَيْئًا صُنِعَ لَهُ كَانَ يَخْطُبُ عَلَيْهِ وَهِيَ أَوَّلُ خُطْبَةٍ خَطَبَهَا فِي الْإِسْلَامِ قَالَ فَحَمِدَ اللَّهَ وَأَثْنَى عَلَيْهِ ثُمَّ قَالَ يَا أَيُّهَا النَّاسُ وَلَوَدِدْتُ أَنَّ هَذَا كَفَانِيهِ غَيْرِي وَلَئِنْ أَخَذْتُمُونِي بِسُنَّةِ نَبِيِّكُمْ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَا أُطِيقُهَا إِنْ كَانَ لَمَعْصُومًا مِنْ الشَّيْطَانِ وَإِنْ كَانَ لَيَنْزِلُ عَلَيْهِ الْوَحْيُ مِنْ السَّمَاءِ‏.‏
