[Machine] The Messenger of Allah ﷺ went out with us in one of the evening prayers of Dhuhr or Asr while carrying one of his sons, either Al-Hasan or Al-Husayn. The Messenger of Allah ﷺ then went forward and placed him at his right foot, and the Messenger of Allah ﷺ prostrated for a long time. My father said, "I raised my head among the people, and behold, the Messenger of Allah ﷺ was prostrating, and the boy was riding on his back. So I went back and prostrated. When the Messenger of Allah ﷺ finished, the people said, 'O Messenger of Allah, you prostrated in this prayer, a prostration we have not seen you do before. Were you commanded to do so, or did something specific inspire you?'" He said, "All of that was not the case, but my son rode on me, so I disliked to hurry him until he had satisfied his need."
خَرَجَ عَلَيْنَا رَسُولُ اللَّهِ ﷺ فِي إِحْدَى صَلَاتِيِ الْعَشِيِّ الظُّهْرِ أَوِ الْعَصْرِ وَهُوَ حَامِلٌ أَحَدِ ابْنَيْهِ الْحَسَنِ أَوِ الْحُسَيْنِ فَتَقَدَّمَ رَسُولُ اللَّهِ ﷺ فَوَضَعَهُ عِنْدَ قَدَمِهِ الْيُمْنَى فَسَجَدَ رَسُولُ اللَّهِ ﷺ سَجْدَةً أَطَالَهَا قَالَ أَبِي فَرَفَعْتُ رَأْسِي مِنْ بَيْنِ النَّاسِ فَإِذَا رَسُولُ اللَّهِ ﷺ سَاجِدٌ وَإِذَا الْغُلَامُ رَاكِبٌ عَلَى ظَهْرِهِ فَعُدْتُ فَسَجَدْتُ فَلَمَّا انْصَرَفَ رَسُولُ اللَّهِ ﷺ قَالَ النَّاسُ يَا رَسُولَ اللَّهِ لَقَدْ سَجَدْتَ فِي صَلَاتِكَ هَذِهِ سَجْدَةً مَا كُنْتَ تَسْجُدُهَا أَفَشَيْءٌ أُمِرْتَ بِهِ؟ أَوْ كَانَ يُوحَى إِلَيْكَ؟ قَالَ «كُلُّ ذَلِكَ لَمْ يَكُنْ وَلَكِنِ ابْنِي ارْتَحَلَنِي فَكَرِهْتُ أَنْ أَعْجَلَهُ حَتَّى يَقْضِيَ حَاجَتَهُ»
