As for the clause: ``So that we might know who...'' and phrases: ``in order to know! that are found in QURÄN; do not mean that God knew not something and later came to know it. God rather has the knowledge of all things before they come to existence, and when it exitsts, adds nothing to the knowledge of God. This may be taken as an architect who has in his drawing all the details of a building, and he constructs a part of the whole building in order to show what he knows.'' As for the question that what becomes of those prayers that they performed towards Jerusalem: to answer it the QURÄN says: ``Your prayers were equally efficacious before the new QIBLA was ordered, and God regards every good act''. ``And never would Allah make Your faith of no effect, for Allah is full of kindness and the Most Merciful to all people.'' God's commandments can be taken in similarity some how to the prescriptions of a physician. One day this order is useful to the patient, and next day another prescription. The change of QIBLA should create no anxiety in some other direction. The east and the west belongs to God, and HE regards all the good acts of HIS servants.
