Spirituality is the direct result of the kind of intellectual development that takes place when a believer ponders over the Creator and His creation
The Holy Quran states in Chapter 4:37: And worship Allah and associate naught with Him and show kindness to parents, and to kindred, and orphans, and the needy, and to the neighbour that is a kinsman and the neighbour that is a stranger, and the companion by your side, and the wayfarer, and those whom your right hand possess (employees). Surely, Allah loves not the proud and the boastful.
