A wise man does think that eating is not just for eating, this eating must be transferred to worship of Allah Almighty, serving the people and being kind toward them. When it is transferred, Allah Almighty seals a persistence on it and says: this worship, this service, this devotion, this kindness and beneficence which you had, is permanent, and this permanence is manifested in the verse of the holy Quran which says:" the gardens wherein streams flow" (Al-Baghara, 25)
