In the words of Imam Askari (AS), if one hundred and twenty-four thousand prophets and we, the fourteen infallibles, are sitting in a line and a true believer passes by us, we will rise in full respect; Because what values a believer is his connection to God and faith in the Resurrection.
God ordered to ask him, we must never say that God knows everything, why should we ask him? because God loves our talking, our voice, our supplication; this is alone a sort of worship; in fact, investing one's voice, tongue, heart is a precious act of worship.
