28-32 Muhammad ibn Musa ibn al-Mutawakkil - may God be pleased with him - narrated that Ali ibn Al-Hussein As-Sa’dabadi quoted on the authority of Ahmad ibn Abi Abdillah al-Barqi, on the authority of Abdul Azeem ibn Abdullah Al-Hassani, on the authority of Abu Ja’far Muhammad ibn Ali Al-Ridha صلى الله عليه وعلى آله وسلم, on the authority of his father Al-Ridha Ali ibn Musa صلى الله عليه وعلى آله وسلم, “I heard from Abul Hassan Musa ibn Ja’far صلى الله عليه وعلى آله وسلم that Amr ibn Obayd al-Basri went to see Abi Abdullah (as-Sadiq) صلى الله عليه وعلى آله وسلم. After greeting him and sitting down, Amr recited the following verse said by the Honorable the Exalted God, ‘Those who avoid great sins and shameful deeds…’ He then became quiet. Abu Abdullah صلى الله عليه وعلى آله وسلم asked himwhy he had become silent. Amr said, “I would like to get to know the great sins from the Book of the Honorable the Exalted God.” The Imam صلى الله عليه وعلى آله وسلم said, “Fine. O Amr! The worst of the great sins is associating partners with God as the Honorable the Exalted God says, ‘…Whoever joins other gods with Allah, Allah will forbid him the Garden, and the Fire will be his abode. There will for the wrong-doers be no one to help.’ The next most important sin is giving up hope of receiving God’s Mercy, since the Honorable the Exalted God says, ‘…and never give up hope of Allah’s Soothing Mercy: truly no one despairs of Allah’s Soothing Mercy, except those who have no faith.’ And feeling secure against the plan of God is also considered to be the next most important sin as the Honorable the Exalted God said, ‘Did they then feel secure against the plan of Allah - but no one can feel secure from the Plan of Allah, except those (doomed) to ruin!’ Also included among the major sins is damnation of parents. Indeed the Honorable the Exalted God has said that the result of parents’ damnation is equal to being overbearing and miserable. Jesus صلى الله عليه وعلى آله وسلم said, ‘(He) hath made me kind to my mother, and not overbearing or miserable.’ Another major sin is killing people - which God has forbidden - except in just cases - as the Honorable the Exalted God says, ‘If a man kills a believer intentionally, his recompense is Hell, to abide therein (Forever): And the wrath and the Curse of God are upon him, and a dreadful penalty is prepared for him.’ Another major sin is slandering chaste women as the Blessed the Sublime God says, ‘Those who slander chaste women, indiscreet but believing, are cursed in this life and in the Hereafter: for them is a grievous Penalty.’ Another major sin is unjustly eating up the property of orphans as the Honorable the Exalted God says, ‘Those who unjustly eat up the property of orphans, eat up a Fire into their own bodies: They will soon be enduring a Blazing Fire!’ Another major sin is escaping from battle as the Honorable the Exalted God says, ‘If any do turn his back to them on such a day - unless it be in a stratagem of war, or to retreat to a troop (of his own) - he draws on himself the wrath of Allah, and his abode is Hell,- an evil refuge (indeed)!’ Another major sin is devouring usury as the Honorable the Exalted God says, ‘Those who devour usury will not stand except as stand one whom the Evil one by his touch Hath driven to madness…’ Another major sin is performing magic as the Honorable the Exalted God says, ‘…And they knew that the buyers of (magic) would have no share in the happiness of the Hereafter…’ Another major sinis committing fornication as the Honorable the Exalted God says, ‘…and any that does this (not only) meets punishment. (But) the Penalty on the Day of Judgment will be doubled to him, and he will dwell therein in ignominy unless he repents, believes, and works righteous deeds, for Allah will change the evil of such persons into good, and Allah is Oft-Forgiving, Most Merciful.’ Another major sin is false swearing as the Honorable the Exalted God says, ‘As for those who sell the faith they owe to Allah and their own plighted word for a small price, they shall have no portion in the Hereafter: Nor will Allah (Deign to) speak to them or look at them on the Day of Judgment, nor will He cleanse them (of sin): They shall have a grievous penalty.’ Another major sin is treason as the Honorable the Exalted God says, ‘…If any person is so false, He shall, on the Day of Judgment, restore what he misappropriated..’ Another major sin is not paying the obligatory alms tax as the Honorable the Exalted God says, ‘On the Day when heat will be produced out of that (wealth) in the fire of Hell, and with it will be branded their foreheads, their flanks, and their backs. This is the (treasure) which ye buried for yourselves: taste ye, then, the (treasures) ye buried!’ Another major sin is giving false testimony as the Honorable the Exalted God says, ‘Those who witness no falsehood…’ And says ‘…for whoever conceals it, His heart is tainted with sin…’ Another major sin is drinking intoxicating drinks as the Honorable the Exalted God has equaled it to idol-worship. Another major sin is willingly abandoning praying or any other obligatory deeds as the Prophet of God صلى الله عليه وعلى آله وسلم said, ‘The ties with God of whoever willingly abandons praying without any reason will be cut off and God and His Prophet صلى الله عليه وعلى آله وسلم will make no covenants with him.’ Another major sin is breaking one’s covenant and ties of kinship as the Honorable the Exalted God says the following about them, ‘…on them is the curse; for them is the terrible home!’ “The narrator added, “Amr ibn Obayd left there while he was crying and saying, ‘I swear by God that whoever debates with you (Imam As-Sadiq صلى الله عليه وعلى آله وسلم) with knowledge and nobility, and still abides by his own points of view, will surely be destroyed.’”
