Messenger of Allah ﷺ said, "Allah said, 'I will declare war against him who shows hostility to a pious worshipper of Mine. And the most beloved things with which My slave comes nearer to Me, is what I have enjoined upon him; and My slave keeps on coming closer to Me through performing Nawafil (praying or doing extra deeds besides what is obligatory) till I love him, so I become his sense of hearing with which he hears, and his sense of sight with which he sees, and his hand with which he grips, and his leg with which he walks; and if he asks Me, I will give him, and if he asks My protection (Refuge), I will protect him; (i.e. give him My Refuge) and I do not hesitate to do anything as I hesitate to take the soul of the believer, for he hates death, and I hate to disappoint him."  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ اللَّهَ قَالَ مَنْ عَادَى لِي وَلِيًّا فَقَدْ آذَنْتُهُ بِالْحَرْبِ وَمَا تَقَرَّبَ إِلَىَّ عَبْدِي بِشَىْءٍ أَحَبَّ إِلَىَّ مِمَّا افْتَرَضْتُ عَلَيْهِ وَمَا يَزَالُ عَبْدِي يَتَقَرَّبُ إِلَىَّ بِالنَّوَافِلِ حَتَّى أُحِبَّهُ فَإِذَا أَحْبَبْتُهُ كُنْتُ سَمْعَهُ الَّذِي يَسْمَعُ بِهِ وَبَصَرَهُ الَّذِي يُبْصِرُ بِهِ وَيَدَهُ الَّتِي يَبْطُشُ بِهَا وَرِجْلَهُ الَّتِي يَمْشِي بِهَا وَإِنْ سَأَلَنِي لأُعْطِيَنَّهُ وَلَئِنِ اسْتَعَاذَنِي لأُعِيذَنَّهُ وَمَا تَرَدَّدْتُ عَنْ شَىْءٍ أَنَا فَاعِلُهُ تَرَدُّدِي عَنْ نَفْسِ الْمُؤْمِنِ يَكْرَهُ الْمَوْتَ وَأَنَا أَكْرَهُ مَسَاءَتَهُ
