ذِكْرُ الْإِبَاحَةِ لِلْمَرْءِ أَنْ يُطَوِّلَ الرَّكْعَةَ الْأُولَى مِنْ صَلَاتِهِ رَجَاءَ لُحُوقِ النَّاسِ صَلَاتَهُ إِذَا كَانَ إِمَامًا

[Machine] About the prayer of the Prophet ﷺ , he said, "There is no good for you in that. The prayer was established for the Prophet ﷺ , so one of us would go out to Al-Baqi to fulfill his needs, then he would come and perform ablution and find the Messenger of Allah ﷺ in the first rak'ah of Dhuhr prayer."  

ابن حبّان:١٨٥٤ – أَخْبَرَنَا أَحْمَدُ بْنُ عَلِيِّ بْنِ الْمُثَنَّى قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ قَالَ حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ عَنْ مُعَاوِيَةَ بْنِ صَالِحٍ عَنْ رَبِيعَةَ بْنِ يَزِيدَ عَنْ قَزَعَةَ قَالَ سَأَلْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ

عَنْ صَلَاةِ النَّبِيِّ ﷺ قَالَ لَيْسَ لَكَ فِي ذَلِكَ خَيْرٌ «كَانَتِ الصَّلَاةُ تُقَامُ لِلنَّبِيِّ ﷺ فَيَخْرُجُ أَحَدُنَا إِلَى الْبَقِيعِ لِيَقْضُيَ حَاجَتَهُ ثُمَّ يَجِيءُ فَيَتَوَضَّأُ فَيَجِدُ رَسُولَ اللَّهِ ﷺ فِي الرَّكْعَةِ الْأُولَى مِنَ الظُّهْرِ»

“I asked Abu Sa’eed Al-Khudri about the prayer of the Messenger of Allah ﷺ. He said: ‘There is nothing good in that for you.’* I said: ‘Explain it, may Allah have mercy on you.’ He said: ‘The Iqamah would be given for the Zuhr prayer for the Messenger of Allah ﷺ, then one of us would go out to Al- Baqi’, relieve himself, then come back and perform ablution, and he would find the Messenger of Allah ﷺ still in the first Rak’ah of Zuhr.’”
