One of the most crucial attributes of a Muslim is his acceptance of the Qur'an as guidance. One who adopts the Qur'an as his guide is able to consider matters with regard to both himself and the world around him, in the light of the verses of the Qur'an, knowing that it was revealed by Allah, the Creator of not only the Qur'an, but also himself and all that is in the universe. Because Allah is He Who created all things, it is He Who knows the best what is right. Indeed, in verse 14 of the Surat al-Mulk, Allah calls attention to that very fact, stating, “Does He Who created not then know? He is the All-Pervading, the All-Aware.” Al-Khabir, that is, “the All-Aware”, which is the attribute of Allah mentioned in the verse, means the One Who is aware of the inner and secret aspect of all things.
