You will never attain virtue till you are spending from whatever you are loving, and whatever you are spending from anything, then indeed, Lord Allah Knows with It.
This verse commands the believers to spend from whatever they are loving. Since Lord is the Three-Time-Knower, there is no need of boasting about charity given to others. Prayers and the charity of the Fujjar are in vain since they made their food ‘rejecting Adhikr’. They will get Hell as a penalty for their aimless and heedless life in this world as told in verse 25: 65-66. They are destined to the seven doors of Hell as told in verse 15: 44. By not utilizing the bestowed intelligence, they are not even considered as human beings as explained in verse 8: 22. See explanation 2: 177, 186, 267 and 9: 53-55.
