Every creature is accountable to Allah. If the God’s genuine servant realize this fact, he would be free from all life-less and living idols and would arrive at the true liberation. This is due to the fact that Allah is the Real Judge.
Another meaning of Al-Hasib is that He summons all creatures to account for them. Still another meaning of this expression is that at the Doom’s Day, God arranges for rewards or chastisement.
Regarding these irrevocable facts, a true God’s servant relies exclusively on Allah and knows that Allah is the source for his sustenance and his other affairs and is careful of his deeds since he knows that he is accountable to Allah at Doom’s Day.
Considering these facts, a true believer relies only on God and on nothing else.
