1. 3:159 فَبِمَا رَحْمَةٍ مِّنَ ٱللَّهِ لِنتَ لَهُمْ وَلَوْ كُنتَ فَظًّا غَلِيظَ ٱلْقَلْبِ لَٱنفَضُّوا۟ مِنْ حَوْلِكَ فَٱعْفُ عَنْهُمْ وَٱسْتَغْفِرْ لَهُمْ وَشَاوِرْهُمْ فِى ٱلْأَمْرِ فَإِذَا عَزَمْتَ فَتَوَكَّلْ عَلَى ٱللَّهِ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُتَوَكِّلِينَ

   Thus it is due to mercy from Allah that you deal with them gently, and had you been rough, hard hearted, they would certainly have dispersed from around you; pardon them therefore and ask pardon for them, and take counsel with them in the affair; so when you have decided, then place your trust in Allah; surely Allah loves those who trust.
   

2. 20:44 فَقُولَا لَهُۥ قَوْلًا لَّيِّنًا لَّعَلَّهُۥ يَتَذَكَّرُ أَوْ يَخْشَىٰ

   Then speak to him a gentle word haply he may mind or fear.
   

3. 34:10 وَلَقَدْ ءَاتَيْنَا دَاوُۥدَ مِنَّا فَضْلًا يَٰجِبَالُ أَوِّبِى مَعَهُۥ وَٱلطَّيْرَ وَأَلَنَّا لَهُ ٱلْحَدِيدَ

   And certainly We gave to Dawood excellence from Us: O mountains! sing praises with him, and the birds; and We made the iron pliant to him,
   

4. 39:23 ٱللَّهُ نَزَّلَ أَحْسَنَ ٱلْحَدِيثِ كِتَٰبًا مُّتَشَٰبِهًا مَّثَانِىَ تَقْشَعِرُّ مِنْهُ جُلُودُ ٱلَّذِينَ يَخْشَوْنَ رَبَّهُمْ ثُمَّ تَلِينُ جُلُودُهُمْ وَقُلُوبُهُمْ إِلَىٰ ذِكْرِ ٱللَّهِ ذَٰلِكَ هُدَى ٱللَّهِ يَهْدِى بِهِۦ مَن يَشَآءُ وَمَن يُضْلِلِ ٱللَّهُ فَمَا لَهُۥ مِنْ هَادٍ

   Allah has revealed the best announcement, a book conformable in its various parts, repeating, whereat do shudder the skins of those who fear their Lord, then their skins and their hearts become pliant to the remembrance of Allah; this is Allah's guidance, He guides with it whom He pleases; and (as for) him whom Allah makes err, there is no guide for him.
   

5. 59:5 مَا قَطَعْتُم مِّن لِّينَةٍ أَوْ تَرَكْتُمُوهَا قَآئِمَةً عَلَىٰٓ أُصُولِهَا فَبِإِذْنِ ٱللَّهِ وَلِيُخْزِىَ ٱلْفَٰسِقِينَ

   Whatever palm-tree you cut down or leave standing upon its roots, It is by Allah's command, and that He may abase the transgressors.
