God, in virtue of His name Qabdh, grips man's heart and puts him into a state of qabdh (literally, "contraction," "gripping"); a state of spiritual desolation, which is a test for man to see his level of determination and loyalty. That is, the man is tested to see whether he will turn to God and do prayers and supplications—or turn away. Let me point out here that prayers, supplications, duties and services done in such a state are far more rewarding than those done at bast (literally, "expansion," "extension"), in a joyful and happy state, or than those done with ease, amid other Muslims at normal times of congregation. And later on, as the sun shines after a short burst of cloudy weather, God, in virtue of His name Basit, expands the man's heart and returns him to comfort and eagerness. Thus, God gives man the reward proportionately to the hardship he endures.
