غسل اليدين قبل الطعام وبعده
A hygiene practice distinct from the existing 'washing hands after waking' entry — washing before and after eating specifically, tied by the hadith to blessing in one's provision.
مَنْ أَحَبَّ أَنْ يُبَسَّطَ لَهُ فِي رِزْقِهِ ... فَلْيَتَوَضَّأْ عِنْدَ طَعَامِهِ
“Whoever wishes to have his provision expanded... let him perform ablution (wash the hands) at his meal.” (meaning, not a literal translation)
Later commentators read this alongside general Prophetic table manners — eating with the right hand, starting with Bismillah — as part of a coherent hygiene-and-etiquette framework around meals.
