These nine verses therefore contain exhortation and warning: they awaken in the believers longing to hasten towards good, that is, spending in the way of Allah in ease as well as in straitness, restraining their anger and forgiving the people's faults; all is joined together under the heading of spreading good in the society, patience in face of grievance and injury, and refraining from repaying evil with evil. It is the only way of preserving the society and making it strong and energetic.

Refraining from interest is a very important concomitant of this spending benevolently and doing good to others. That is why the verses begin with it; it paves the way for exhortation to good-doing and spending.

We have already explained — under the verses of spending and interest in the chapter of The Cow — that spending in all its aspects is the cornerstone of society; it is the virtue that vitalizes the human society with the spirit of unity; it channels its scattered resources to achieve happiness and felicity in this life, and strengthens it to ward off every pernicious perversion. Interest is diametrically opposed to benevolent spending in this respect. Allah exhorts them to these virtues.

Then He encourages them to return to their Lord again and again even if they have committed sins and errors; they should not lose hope of His mercy even if they have done something which is not liked by Him; they must repent and seek pardon from Him repeatedly without indolence or negligence. By doing good to others and returning to Allah in time and again, they would proceed on the straight path of happy life; they will never go astray nor will they stop at any dangerous point.

This Qur'anic description is the best way for guiding man to perfect himself when he finds some defects in his life; the finest means of curing spiritual ailments which sometimes creep into otherwise good souls and threaten man with downfall and ruin. QUR'AN: O you who believe! do not devour interest . . . that you may be shown mercy: We have explained how "devouring" is used for "taking ".

The phrase, "making it double and redouble ", points to overriding characteristic of interests; interest, per se, multiplies and increases the lender's wealth many-fold by depleting debtor's money adding it to the creditor's capital.
