(Imam). The imam is 'the one who is followed'. When the heart has been purified through spiritual endeavour and love of Allah it becomes worthy of being the place which will contain Allah. Such a heart is the real imam, the truthful leader, who is to be followed in the prayer. The sanctified heart has the means to guide and lead the intellect to Knowledge of Allah. Al Khidr, the Green Prophet (Peace be upon him) is likened to the heart and the Prophet Musa (Peace be upon him) is likened to the intellect. And al Khidr said, "Truly you will not be able to have patience with me. And how can you have patience about things about which your understanding is not complete?" (The Qur'an 18:6-68). When the heart leads the intellect, albeit momentarily, then True Knowledge of Allah descends into that heart.
