As long as their wealth went on increasing and there was no occasion of disease and loss, horses went on breeding, wives continued to produce male offspring; they used to say that Muhammad is an auspicious man and his religion is truth. But when the climate of Medina did not suit them and they became sick. Their animals started dying, they started saying, this magician Muhammad (we seek Allah's refuge) is inauspicious and his religion is baseless. He has given us nothing except loss and misery.
It is evident from this noble verse that people having doubt (about religion) are at a loss in this world as well as in the Hereafter. In fact, doubt is an impurity of the heart. It is obligatory on every person to keep his heart clean of this impurity and adorn it with the effulgence of monotheism. Do not doubt! You may become an infidel Imam Husain (a.s.) arrived in Karbala’ on the second day of Mohurrum in the year 61 Hijri.
Whatever he said addressing the army of Yazid, explains the above-mentioned verse. For more details refer to the books of the Karbala’ tragedy. Amirul Momineen Ali (a.s.) in one of his sermons says, “Do not become prey to wavering (suspense), otherwise your doubt will become strong and do not get entangled in doubt, otherwise you will become an infidel.” Allamah Majlisi has said, “It means that do not even go near such things that may put you into doubt.
Or may be it means that you should not become unhappy by what Allah has ordained for you, because such an attitude also becomes the cause of doubt, and wavering and uncertainty are the initial forms of doubt.” One who doubts in Allah is an infidel In the chapter of Doubt in Usul al-Kafi there is a tradition that Muhammad bin Muslim says, “I was sitting on the left side of Imam Ja'far as-Sadiq (a.s.) and Zurarah on his right. In the meantime Abu Basir arrived. Abu Basir asked, 'O Aba Abdillah!
What do you say regarding a person who doubts about Allah?' Imam said, 'He is an infidel.' Muhammad bin Muslim says, “After that Imam turned towards Zurarah and said, 'If he openly denies then he certainly becomes an infidel.'” In this tradition Imam Ja'far as-Sadiq (a.s.) has said that a person who is apparently a Muslim, but in his heart, he has doubt about Allah and the Prophet, and he dies in this same condition, he will be included among the infidels.
