He is One .
He is One .There is no partner with Him and that Mohammad is the Messenger of Allah and that Ali is the just Imam after him, then Hassan and Hossain, then Ali ibn al-Hossain, then Mohammad ibn Ali, and then you.’ The Imam (AS) said: ‘May Allah have mercy on you!’ Then, he said: ‘Fear Allah, fear Allah, fear Allah!
It is incumbent on you to be pious, truthful in speaking, to give back trusts (to their owners), be chaste in belly (not to eat any ill-gotten thing) and private parts (chaste in sexual intercourse), in order to be good friend of us.”[^10] Imam Sadiq (AS) has been reported as saying: “There are four features in one whose faith is perfect …; truthfulness, giving the trust (back to its owner), decency and good temper.”[^11] In Ameerul Mo’minin’s description of pious men, the first feature he mentions is that their speech is to the point.
The second feature of the pious, mentioned in the first verse aforementioned, “he who accepts it as the truth”, we should say that so long as one does not believe in the truth, in God, in the Messenger, in the unseen and visible world, the divine rules, the religious laws, and in all what God has sent of prophets and books, cannot be pious. Hence, we consider Imam Ali (AS) as the true example of the pious.
The Messenger of Allah (SAW) has been reported as saying: “The truthful ones are three; Ali ibn Abi Talib, Habeeb the carpenter, and the believer of the people of the Pharaoh.”[^12] (2) Another feature with which we can know the pious is the belief in the Unseen which includes the belief in God, the Prophet, his successors including Imam (AS) Mahdi (AS), the belief in what was revealed to the Holy prophet, the Last Day, Resurrection, Sirat (the Straight Way),[^13] Balance, Reckoning, Paradise and Hell as God has said: “And who believe in that which has been revealed to you and that which was revealed before you and they are sure of the hereafter.” [^14] Belief is of several kinds: 1- The belief in God and His Attributes 2- The belief in the Messenger of Allah (SAW) and his qualities 3- The belief in what the prophets have brought 4- The belief in their successors and in their specifications 5- The belief in the hereafter with all its specifications 6- The belief in the angels A person may have Belief in God, but not in His Attributes.
He may believe in God, but he does not consider God as Just. He may believe in God but not in the messenger of God.
