Oh, you who believed, you spend from the wholesome things you have earned, and from what We have produced from the earth for you; and you don’t intend to spend the impure from it which you yourselves would not accept except with disdain, and you know that Lord Allah is the Self-Sufficient, Praiseworthy.
The believer only earns and spends anything under the Light of Adhikr which is the Lord’s Permission. He doesn’t earn anything in illegal ways. He is always in a consciousness that the Lord is witnessing and observing upon everything. But the Arabic Quran reading Fujjar by forgetting the Lord’s Book are earning impure things through interest, gambling, smuggling, bribery, receiving dowry from the female side, robbery, adulteration, black money, cheating, and all such Satanic footsteps as explained in verses 2: 168-169. It is told in verse 5: 100: “Bad and Good are not equal even though the abundance of the bad wonders you, so you heed Lord Allah, oh you the People endowed with intelligence, so that you may prosper”.
By calling the believers it is told in verse 9: 34: “Indeed, most of the anchorites and priests are eating the wealth of people in falsehood ways and are obstructing them from the Straightpath Adhikr”. Lord asks through verse 5: 63: “Why don’t their anchorites and their priests forbid the people from uttering sinful words and eating prohibited things? Indeed, wretched is what they are producing”. It is told in verse 4: 140: “If you hear Lord’s verses being rejected or ridiculed, you shouldn’t sit with them until they engage in some other speeches, if you do so you would be like them, indeed, Lord will gather the hypocrites and the disbelievers all together in the Hell”. The Fujjar are denoted as the worst creatures for not due to not hearing the Arabic Quran and talking about It, but it is due to not hearing Adhikr and talking about It as told in verse 8: 22. See explanation 2: 172; 6: 141 and 16: 114.
