Here Allah tells us that He defends His servants who put their trust in Him and turn to Him in repentance; He protects them from the the worst of evil people and the plots of the sinners; He protects them, guards them and supports them, as He tells us elsewhere:

[أَلَيْسَ اللَّهُ بِكَافٍ عَبْدَهُ]

(Is not Allah sufficient for His servant) [39:36]

[وَمَن يَتَوَكَّلْ عَلَى اللَّهِ فَهُوَ حَسْبُهُ إِنَّ اللَّهَ بَـلِغُ أَمْرِهِ قَدْ جَعَلَ اللَّهُ لِكُلِّ شَىْءٍ قَدْراً]

(And whosoever puts his trust in Allah, then He will suffice him. Verily, Allah will accomplish his purpose. Indeed Allah has set a measure for all things) [65:3].

[إِنَّ اللَّهَ لاَ يُحِبُّ كُلَّ خَوَّانٍ كَفُورٍ]

(Verily, Allah likes not any treacherous ingrate) means, He does not like any of His servants who bear these characteristics, i.e., treachery in covenants and promises whereby a person does not do what he says, and ingratitude is to deny the blessings, whereby one does not acknowledge or appreciate them.

[أُذِنَ لِلَّذِينَ يُقَـتَلُونَ بِأَنَّهُمْ ظُلِمُواْ وَإِنَّ اللَّهَ عَلَى نَصْرِهِمْ لَقَدِيرٌ - الَّذِينَ أُخْرِجُواْ مِن دِيَـرِهِم بِغَيْرِ حَقٍّ إِلاَّ أَن يَقُولُواْ رَبُّنَا اللَّهُ وَلَوْلاَ دَفْعُ اللَّهِ النَّاسَ بَعْضَهُمْ بِبَعْضٍ لَّهُدِّمَتْ صَوَمِعُ وَبِيَعٌ وَصَلَوَتٌ وَمَسَـجِدُ يُذْكَرُ فِيهَا اسمُ اللَّهِ كَثِيراً وَلَيَنصُرَنَّ اللَّهُ مَن يَنصُرُهُ إِنَّ اللَّهَ لَقَوِىٌّ عَزِيزٌ ]

(39. Permission (to fight) is given to those (believers) who are fought against, because they have been wronged; and surely, Allah is able to give them victory.) (40. Those who have been expelled from their homes unjustly only because they said: "Our Lord is Allah.'' For had it not been that Allah checks one set of people by means of another, Sawami`, Biya`, Salawat, and Masjids, wherein the Name of Allah is mentioned much, would surely have been pulled down. Verily, Allah will help those who help His (cause). Truly, Allah is All-Strong, All-Mighty.)
