Sunnah's of eating
NABI صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ said "washing the hands before and after meals repels poverty and it is the sunnah of all the Ambiya Alayhimus Salam"
NABI صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ said "if a man enters his home, and takes the name of ALLAH and partakes of his meal after taking the name of ALLAH, then shaytan says to his companions," There is no sleeping place nor any food for you here."
NABI صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ said "Take the name of ALLAH, eat with the right hand and eat the food that is directly in front of you."
NABI صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ said " The utensil of the person who cleans it thoroughly supplicates saying," O ALLAH! Save him from the fire of Jahannum as he saved me from shaytan"
Note: The utensil is sinless and its supplication will definitely be accepted. (According to a verse in the Quraan Majid, ALLAH ta'ala declares that every creation of His glorifies Him in a manner that is imperceptible to humans. Thus, it's seeking forgiveness on behalf of such people is justified through this verse.)
