Islam strictly prohibits the business of religion. Holy Quran castigates those who manipulate religious scriptures in order to do business out of it. A Hadith says that those who seek the knowledge of the religion for the purpose of hoarding material benefits of this world will be deprived of the rewards of the hereafter.
- Al-Quran 2:78 There are among them unlettered people who have no real knowledge of the Scriptures, knowing only their own wishful thinking and following only conjecture. Woe to those who write the scripture with their own hands, and then declare, ‘This is from God,’ in order to sell it for a paltry price. Woe to them because of what their own hands have written, and woe to them for what they have earned.
- Al-Quran 3:187-188 God made a covenant with those who were given the Book to make it known to people and not conceal it. But they cast it behind their backs and bartered it for a paltry price: what an evil bargain they made! Those who exult in their misdeeds and love to be praised for what they have not done should not suppose that they are secure from punishment; they shall suffer a grievous punishment.
- Al-Quran 42:23 It is that of which Allah gives good tidings to His servants who believe and do righteous deeds. Say, [O Muhammad], “I do not ask you for this message any payment [but] only good will through kinship.” And whoever commits a good deed – We will increase for him good therein. Indeed, Allah is Forgiving and Appreciative.
- Miskat-ul Masabeeh 227- Narrated Abu Hurairah (r)- Messenger of Allah said- “A person who seeks the knowledge (which is for pleasing God) just for the sake earning the material benefits of this world will not be entitled to rewards of the hereafter.”
