349 This is the prayer of those who are firmly grounded in knowledge. The more they know, the more they realise how little they know of all the depths of Truth in the spiritual worlds. But they have Faith. The glimpses they get of Truth they wish to hold fast in their hearts, and they pray to Allah to preserve them from deviating even from what light they have got. They are sure of their eventual return to Allah, when all doubts will be solved.
