Bismillah

The Arabic phrase Bismillah ir-Rahman ir-Rahim is a beautifully poetic expression which offers both insight and inspiration. It has often been said that the phrase Bismillah ir-Rahman ir-Rahim contains the true essence of the entire Qur'an, as well as the true essence of all religions.

Muslims often say the phrase when embarking on any significant endeavor, and the phrase is considered by some to be a major pillar of Islam. This expression is so magnificent and so concise that all but one chapter of the Qur'an begins with the words Bismillah ir-Rahman ir-Rahim.

The common translation as:

"In the name of God, most Gracious, most Compassionate".

fails to capture either the true depth of meaning or the inspirational message of this beautiful phrase.
