Ya ayyuha allatheena amanoo la ta'kuloo amwalakum baynakum bilbatili illa an takoona (surah Nisa: 29)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(4:29) Believers! Do not devour one another's possessions wrongfully; rather than that, let there be trading by mutual consent. *50 You shall not kill yourselves. *51 Surely Allah is ever Compassionate to you. *52

Yaaa aiyuhal lazeena aamanoo laa taakulooo amwaalakum bainakum bilbaatili `illaaa an takoona tijaaratan `an taraadim minkum; wa laa taqtulooo anfusakum; innal laaha kaana bikum Raheemaa

*50). The expression 'wrongfully' embraces all transactions which are opposed to righteousness and which are either legally or morally reprehensible. By contrast, 'trade' signifies the mutual transfer of benefits between the parties concerned, such as that underlying those transactions in which one person provides whatever satisfies the needs of another person and is paid in return. 'Mutual consent' means that the exchange should be free of undue pressure, fraud and deception. Although bribery and interest apparently represent transactions based on mutual consent, closer examination reveals that such consent takes place by constraint and under pressure. In games of chance, too, the participants seem to consent freely to the outcome. This kind of consent, however, is due to the expectation entertained by the participants that they will win. No one takes part anticipating loss. Fraudulent transactions also seem to be based on the mutual consent of the parties concerned. That kind of consent, however, is based on the false assumption that no fraud is involved in the transaction. Nobody who knew that he would be subjected to fraud would consent to be a party to that transaction.
*51). This can be considered either as complementary to the preceding sentence or as an independent statement. If it is complementary, it means that to consume the property of others by wrongful means is tantamount to courting one's own destruction; for such practices corrupt society on such a scale that even the most cunning are not spared their destructive consequences. This is in addition to the severe punishment that is bound to be meted out to such people in the Next Life. Taken as an independent statement, it can mean either that one should not kill others or that one should not kill oneself. Both the words used and the sequence in which they have been placed by God in this verse make each of these three meanings feasible.
*52). God wishes His creatures well; their well-being and salvation please Him, and it is out of benevolence that He has forbidden things harmful to human beings.
