Most of them require spiritual therapy. This active type of prayer is usually acceptable, for it is a direct application to the Divine Name the All-Generous. The second type of prayer, which is done with the tongue and the heart, is the real one. It is to ask God from the heart for something that we cannot obtain on our own. The most important aspect of this sort of prayer, and its finest and sweetest fruit, is that the supplicants know that He hears them, is aware of whatever occurs to their hearts, has power that extends everywhere, can satisfy all their desires, and helps them because He is merciful to the weak and helpless.
Prayer is a form of worship rewarded primarily in the Hereafter.
For this reason, we must not say that are prayers are not answered when we do not receive what we pray for. Just because a prayer is answered does not mean that it is accepted in all circumstances. There is an answer for every prayer, but its acceptance and answer depend on God s Wisdom. Suppose a sick child asks a doctor for a certain kind of medicine. The doctor either will give that medicine or something better, or will give no medicine at all, especially if there is some reason to think that it will harm the child.
