Surah 4. An-Nisaa'

88Here the Muslims have been fore-warned that they should avoid those evils in which the children of Israel were involved. Their basic error was that during their degeneration they entrusted the positions of trust to incompetent people. They began to entrust positions of responsibility and religious and political leadership to inefficient, narrow-minded, immoral, dishonest and wicked people. As a result, the whole community became corrupt. The Muslims are being cautioned against this evil and enjoined to entrust positions of responsibility to qualified and competent people of good moral character.

Another evil that was prevalent among the Jews was injustice. They had lost the very sense and spirit of justice and become utterly unjust, openly dishonest, and sinfully obdurate and would commit acts of gross injustice without any pangs of conscience. The Muslims were personally having a bitter experience of this. The Jews were siding with the idolatrous Quraish against the Believers in one God though the lives of the two clearly showed "who was more rightly guided."On the one side, they saw the pure lives of the Holy Prophet and his followers; on the other, they witnessed the immoral lives of their enemies, who buried their daughters alive, married their step mothers and went round the Ka`bah in naked state. Still these "people of the Book" preferred the idolatrous people to the. Believers and brazen-facedly declared that the former were more rightly guided than the latter. Allah warns the Believers against this sort of injustice and enjoins them always to say what is just and right and judge between the people with justice whether they be friends or foes.
