[3:126] What God ordained was only as a good tiding to you and that your hearts might be at peace. Victory comes only from God, the Mighty, the Wise.
God (s) enacts His practice (sunna) with His friends is such a way that, when their intentions become weak, their spiritual desire (irāda) low, or their hearts are on the verge of some listlessness; He shows them kindnesses and all kinds of special gifts (karāmāt) which strengthen the means for obtaining their mystical knowledge (irfān) and reinforce the realities of their certainty. According to this practice, He sent down this address, and then separated their hearts and innermost selves from anything other than Him entirely, and He said: Victory comes only from God.
