Sahih al-Bukhari 1207
Narrated Mu'aiqib:
The Prophet ﷺ talked about a man leveling the earth on prostrating, and said, "If you have to do so, then do it once."
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا شَيْبَانُ، عَنْ يَحْيَى، عَنْ أَبِي سَلَمَةَ، قَالَ حَدَّثَنِي مُعَيْقِيبٌ، أَنَّ النَّبِيَّ ﷺ قَالَ فِي الرَّجُلِ يُسَوِّي التُّرَابَ حَيْثُ يَسْجُدُ قَالَ
" إِنْ كُنْتَ فَاعِلاً فَوَاحِدَةً ".
