The Ahadeeth tell us what we must recite Bismillaahir Rahmaanir Raheem (In the Name of Allaah, The Most Beneficent, The Most Merciful.) before we begin eating.
If we think about it, when we recite Bismillaahir Rahmaanir Raheem, we get lots of reward from Allaah and at the same time, we also get to think of Allaah.
In fact, the purpose of reciting Bismillaahir Rahmaanir Raheem is to remind us that it is Allaah Who gave us this food and not my effort and intelligence.
I should remember that it is not possible for me to arrange for this food to come to me and to satisy my hunger. It is only by the kindness of Allaah that I have this food to eat.
