٦٠. لَّئِن لَّمْ يَنتَهِ ٱلْمُنَـٰفِقُونَ وَٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌ وَٱلْمُرْجِفُونَ فِى ٱلْمَدِينَةِ لَنُغْرِيَنَّكَ بِهِمْ ثُمَّ لَا يُجَاوِرُونَكَ فِيهَآ إِلَّا قَلِيلًا
٦١. مَّلْعُونِينَ ۖ أَيْنَمَا ثُقِفُوٓا۟ أُخِذُوا۟ وَقُتِّلُوا۟ تَقْتِيلًا
٦٢. سُنَّةَ ٱللَّهِ فِى ٱلَّذِينَ خَلَوْا۟ مِن قَبْلُ ۖ وَلَن تَجِدَ لِسُنَّةِ ٱللَّهِ تَبْدِيلًا
[60-62] If the hypocrites and those whose hearts are diseased113 and the scandal-mongers in Madinah114 do not desist, We shall stir you up to take action against them; then they will hardly be able to live in this city as your neighbors. They will be cursed from every side and will be seized wherever they are found and killed mercilessly. This has been the Way of Allah with regard to such people before, and you will never find any change in the Way of Allah.115
113"Having diseased hearts" points to two kinds of evils:
(1) That a person should be an ill-wisher of Islam and the Muslims although he gets himself counted among the Muslims; and
(2) that he should be cherishing evil intentions and having criminal mentality and his evil tendencies be manifesting themselves in everything he thinks and does.
114This implies the people who, in order to cause panic among the Muslims and to lower their morale, used to spread rumors in Madinah to the effect that the Muslims had suffered such and such serious setback, that a huge army was gathering together against them at such and such a place, that Madinah was under threat of a sudden attack, etc. Besides this, they had another pastime. they would concoct and spread imaginary stories about the domestic life of the Holy Prophet's household and of other Muslims so as to produce suspicions among the common people and destroy the moral influence of the Muslims.
115That is, "This is a permanent law of Allah's Shari'ah that in an Islamic society and state such mischief-mongers are never given an opportunity to flourish and prosper. Whenever the system of society and state is established on Divine Law, such people will be warned to mend their ways and if they still persisted in their evil ways they would be severely dealt with and exterminated."
