Give food to the hungry
Narrated by Abu Musa Al Ashari(Radhiallaho anho):
Allah’s Messenger (sallallaahu ‘alaihi wasallam) said, “Give food to the hungry, pay a visit to the sick and release (set free) the one in captivity (by paying his ransom).”

Mentioning Allah’s Name on starting to eat
Narrated by Umar bin Abi Salama(Radhiallaho anho):
I was a boy under the care of Allah’s
Messenger (sallallaahu ‘alaihi wasallam) and my hand used to go around the dish while I was eating. So Allah’s Apostle said to me, “O boy! Mention the Name of Allah and eat with your right hand, and eat of the dish what is nearer to you.” Since then I have applied those instructions when eating.

Eating with the right hand
Narrated by Aisha(Radhiallaho anha):
Allah’s Messenger (sallallaahu ‘alaihi wasallam) used to love to start doing things from the right side whenever possible, in performing ablution, putting on his shoes, and combing his hair. (Al-Ash’ath said: The Prophet used to do so in all his affairs.)

A beliver is satisfied with a little food
Narrated by Abu Huraira(Radhiallaho anho):
A man used to eat much, but when he embraced Islam, he started eating less. That was mentioned to Allah’s Messenger (sallallaahu ‘alaihi wasallam), who then said, “A believer eats in one intestine (is satisfied with a little food) and a Kafir eats in seven intestines (eats much).”
