Man possesses a double personality. Therefore, two types of provision are to be constantly supplied for him to survive. One being physical provision, the other being spiritual provision. The centre of the acquisition of physical provision, according to the Qur’an, is this earth (14:32) and the centre of the acquisition of spiritual provision is the Being of God. That is why this provision is called ‘Lord’s sustenance’ (20:131) or ‘spiritual provision’ is, in actual fact, the result of a contact with the external source of sustenance – that is, God.
