[Machine] The Messenger of Allah (PBUH) preferred to pray on a carpet or a mat.  

«كَانَ رَسُولُ اللهِ ﷺ يَسْتَحِبُّ أَنْ يُصَلِّيَ عَلَى فَرْوَةٍ مَدْبُوغَةٍ أَوْ حَصِيرٍ»  

[Machine] He accompanied the Prophet ﷺ and entered some of those valleys, then he entered them and fulfilled his need, then he came out and performed ablution and took off his socks. When he put them back on, he smelled a scent, so he returned and performed ablution and wiped over his socks. I said, "Did you forget, O Prophet of Allah?" He said, "No, but you forgot the command of my Lord."  

أَنَّهُ مَشَى مَعَ النَّبِيِّ ﷺ فَأَتَى بَعْضَ تِلْكَ الْأَوْدِيَةِ فَدَخَلَهَا فَقَضَى حَاجَتَهُ ثُمَّ خَرَجَ فَتَوَضَّأَ وَخَلَعَ الْخُفَّيْنِ فَلَمَّا لَبَسَ وَجَدَ بَعْدَ ذَلِكَ رِيحًا فَعَادَ فَتَوَضَّأَ وَمَسَحَ عَلَى الْخُفَّيْنِ فَقُلْتُ أَنَسِيتَ يَا نَبِيَّ اللهِ؟ قَالَ «لَا بَلْ أَنْتَ نَسِيتَ بِهَذَا أَمَرَنِي رَبِّي ﷻ»  

[Machine] The Messenger of Allah ﷺ performed ablution and wiped over his socks. So I said, "O Messenger of Allah, did you forget?" He replied, "No, but you forgot that my Lord commanded me to do so."  

تَوَضَّأَ رَسُولُ اللهِ ﷺ وَمَسَحَ عَلَى خُفَّيْهِ فَقُلْتُ يَا رَسُولَ اللهِ أَنَسِيتَ؟ قَالَ «بَلْ أَنْتَ نَسِيتَ بِهَذَا أَمَرَنِي رَبِّي»
