Chastising the hypocrites, Allah said,

﴿فَكَيْفَ إِذَآ أَصَـبَتْهُمْ مُّصِيبَةٌ بِمَا قَدَّمَتْ أَيْدِيهِمْ﴾

(How then, when a catastrophe befalls them because of what their hands have sent forth,) meaning, how about it if they feel compelled to join you because of disasters that they suffer due to their sins, then they will be in need of you.

﴿ثُمَّ جَآءُوكَ يَحْلِفُونَ بِاللَّهِ إِنْ أَرَدْنَآ إِلاَّ إِحْسَاناً وَتَوْفِيقاً﴾

(They come to you swearing by Allah, "We meant no more than goodwill and conciliation!'') apologizing and swearing that they only sought goodwill and reconciliation when they referred to other than the Prophet for judgment, not that they believe in such alternative judgment, as they claim. Allah describes these people to us further in His statement,

﴿فَتَرَى الَّذِينَ فِى قُلُوبِهِم مَّرَضٌ يُسَـرِعُونَ فِيهِمْ يَقُولُونَ نَخْشَى﴾

(And you see those in whose hearts there is a disease (of hypocrisy), they hurry to their friendship, saying: "We fear''), until,

﴿فَيُصْبِحُواْ عَلَى مَآ أَسَرُّواْ فِى أَنفُسِهِمْ نَـدِمِينَ﴾

(Then they will become regretful for what they have been keeping as a secret in themselves). At-Tabarani recorded that Ibn `Abbas said, "Abu Barzah Al-Aslami used to be a soothsayer who judged between the Jews in their disputes. When some Muslims came to him to judge between them, Allah sent down,

﴿أَلَمْ تَرَ إِلَى الَّذِينَ يَزْعُمُونَ أَنَّهُمْ ءَامَنُواْ بِمَآ أُنزِلَ إِلَيْكَ وَمَآ أُنزِلَ مِن قَبْلِكَ﴾

(Have you not seen those (hyprocrites) who claim that they believe in that which has been sent down to you, and that which was sent down before you), until,

﴿إِنْ أَرَدْنَآ إِلاَّ إِحْسَاناً وَتَوْفِيقاً﴾

("We meant no more than goodwill and conciliation!'') Allah then said,

﴿أُولَـئِكَ الَّذِينَ يَعْلَمُ اللَّهُ مَا فِى قُلُوبِهِمْ﴾

(They (hypocrites) are those of whom Allah knows what is in their hearts;) These people are hypocrites, and Allah knows what is in their hearts and will punish them accordingly, for nothing escapes Allah's watch. Consequently, O Muhammad! Let Allah be sufficient for you in this regard, because He has perfect knowledge of their apparent and hidden affairs. This is why Allah said,

﴿فَأَعْرِضْ عَنْهُمْ﴾

(so turn aside from them (do not punish them)) meaning, do not punish them because of what is in their hearts.

﴿وَعِظْهُمْ﴾

(but admonish them) means, advise them against the hypocrisy and evil that reside in their hearts,

﴿وَقُل لَّهُمْ فِى أَنفُسِهِمْ قَوْلاً بَلِيغاً﴾

(and speak to them an effective word to reach their inner selves) advise them, between you and them, using effective words that might benefit them.

﴿وَمَآ أَرْسَلْنَا مِن رَّسُولٍ إلاَّ لِيُطَاعَ بِإِذْنِ اللَّهِ وَلَوْ أَنَّهُمْ إِذ ظَّلَمُواْ أَنفُسَهُمْ جَآءُوكَ فَاسْتَغْفَرُواْ اللَّهَ وَاسْتَغْفَرَ لَهُمُ الرَّسُولُ لَوَجَدُواْ اللَّهَ تَوَّاباً رَّحِيماً - فَلاَ وَرَبِّكَ لاَ يُؤْمِنُونَ حَتَّى يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ ثُمَّ لاَ يَجِدُواْ فِى أَنفُسِهِمْ حَرَجاً مِّمَّا قَضَيْتَ وَيُسَلِّمُواْ تَسْلِيماً ﴾

(64. We sent no Messenger, but to be obeyed by Allah's leave. If they, when they were unjust to themselves, had come to you and begged Allah's forgiveness, and the Messenger had begged forgiveness for them, indeed, they would have found Allah All-Forgiving, Most Merciful.) (65. But no, by your Lord, they can have no faith, until they make you judge in all disputes between them, and find in themselves no resistance against your decisions, and accept (them) with full submission.)
