2. 8:11 إِذْ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةً مِّنْهُ وَيُنَزِّلُ عَلَيْكُم مِّنَ ٱلسَّمَآءِ مَآءً لِّيُطَهِّرَكُم بِهِۦ وَيُذْهِبَ عَنكُمْ رِجْزَ ٱلشَّيْطَٰنِ وَلِيَرْبِطَ عَلَىٰ قُلُوبِكُمْ وَيُثَبِّتَ بِهِ ٱلْأَقْدَامَ

   When He caused calm to fall on you as a security from Him and sent down upon you water from the cloud that He might thereby purify you, and take away from you the uncleanness of the Shaitan, and that He might fortify your hearts and steady (your) footsteps thereby.
   

3. 8:60 وَأَعِدُّوا۟ لَهُم مَّا ٱسْتَطَعْتُم مِّن قُوَّةٍ وَمِن رِّبَاطِ ٱلْخَيْلِ تُرْهِبُونَ بِهِۦ عَدُوَّ ٱللَّهِ وَعَدُوَّكُمْ وَءَاخَرِينَ مِن دُونِهِمْ لَا تَعْلَمُونَهُمُ ٱللَّهُ يَعْلَمُهُمْ وَمَا تُنفِقُوا۟ مِن شَىْءٍ فِى سَبِيلِ ٱللَّهِ يُوَفَّ إِلَيْكُمْ وَأَنتُمْ لَا تُظْلَمُونَ

   And prepare against them what force you can and horses tied at the frontier, to frighten thereby the enemy of Allah and your enemy and others besides them, whom you do not know (but) Allah knows them; and whatever thing you will spend in Allah's way, it will be paid back to you fully and you shall not be dealt with unjustly.
   

4. 18:14 وَرَبَطْنَا عَلَىٰ قُلُوبِهِمْ إِذْ قَامُوا۟ فَقَالُوا۟ رَبُّنَا رَبُّ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ لَن نَّدْعُوَا۟ مِن دُونِهِۦٓ إِلَٰهًا لَّقَدْ قُلْنَآ إِذًا شَطَطًا

   And We strengthened their hearts with patience, when they stood up and said: Our Lord is the Lord of the heavens and the earth; we will by no means call upon any god besides Him, for then indeed we should have said an extravagant thing.
   

5. 28:10 وَأَصْبَحَ فُؤَادُ أُمِّ مُوسَىٰ فَٰرِغًا إِن كَادَتْ لَتُبْدِى بِهِۦ لَوْلَآ أَن رَّبَطْنَا عَلَىٰ قَلْبِهَا لِتَكُونَ مِنَ ٱلْمُؤْمِنِينَ

   And the heart of Musa's mother was free (from anxiety) she would have almost disclosed it had We not strengthened her heart so that she might be of the believers.
