3:118
يَٰٓ أَيُّهَا ٱلَّذِينَ ءَامَنُ وا۟ لَا تَتَّخِذُ وا۟ بِطَانَةً مِّن دُونِ كُمْ لَا يَأْلُ ونَ كُمْ خَبَالًا وَدُّ وا۟ مَا عَنِ تُّمْ قَدْ بَدَتِ ٱلْ بَغْضَآءُ مِنْ أَفْوَٰهِ هِمْ وَ مَا تُخْفِى صُدُورُ هُمْ أَكْبَرُ قَدْ بَيَّ نَّا لَ كُمُ ٱلْ ءَايَٰتِ إِن كُن تُمْ تَعْقِلُ ونَ
O you who have believed, do not take as intimates those other than yourselves, for they will not spare you [any] ruin. They wish you would have hardship. Hatred has already appeared from their mouths, and what their breasts conceal is greater. We have certainly made clear to you the signs, if you will use reason.
49:7
وَ ٱعْلَمُ وٓا۟ أَنَّ فِي كُمْ رَسُولَ ٱللَّهِ لَوْ يُطِيعُ كُمْ فِى كَثِيرٍ مِّنَ ٱلْ أَمْرِ لَ عَنِ تُّمْ وَ لَٰكِنَّ ٱللَّهَ حَبَّبَ إِلَيْ كُمُ ٱلْ إِيمَٰنَ وَ زَيَّنَ هُۥ فِى قُلُوبِ كُمْ وَ كَرَّهَ إِلَيْ كُمُ ٱلْ كُفْرَ وَ ٱلْ فُسُوقَ وَ ٱلْ عِصْيَانَ أُو۟لَٰٓئِكَ هُمُ ٱل رَّٰشِدُونَ
And know that among you is the Messenger of Allah. If he were to obey you in much of the matter, you would be in difficulty, but Allah has endeared to you the faith and has made it pleasing in your hearts and has made hateful to you disbelief, defiance and disobedience. Those are the [rightly] guided.
9:128
لَ قَدْ جَآءَ كُمْ رَسُولٌ مِّنْ أَنفُسِ كُمْ عَزِيزٌ عَلَيْ هِ مَا عَنِ تُّمْ حَرِيصٌ عَلَيْ كُم بِ ٱلْ مُؤْمِنِينَ رَءُوفٌ رَّحِيمٌ
There has certainly come to you a Messenger from among yourselves. Grievous to him is what you suffer; [he is] concerned over you and to the believers is kind and merciful.
