The Prophet (صلى الله عليه وسلم) told us that his Lord said:
وَمَا تَقَرَّبَ إِلَيَّ عَبْدِي بِشَيْءٍ أَحَبَّ إِلَيَّ مِمَّا افْتَرَضْتُ عَلَيْهِ
وَمَا يَزَالُ عَبْدِي يَتَقَرَّبُ إِلَيَّ بِالنَّوَافِلِ حَتَّى أُحِبَّهُ
فَإِذَا أَحْبَبْتُهُ كُنْتُ سَمْعَهُ الَّذِي يَسْمَعُ بِهِ
وَبَصَرَهُ الَّذِي يُبْصِرُ بِهِ وَيَدَهُ الَّتِي يَبْطِشُ بِهَا
وَرِجْلَهُ الَّتِي يَمْشِي بِهَا
وَإِنْ سَأَلَنِي لأُعْطِيَنَّهُ وَلَئِنْ اسْتَعَاذَنِي لأُعِيذَنَّهُ
“My slave does not draw near to Me with anything more beloved to Me than the religious duties I have enjoined upon him, and My slave continues to draw near to Me with supererogatory works so that I will love him, When I love him, I am his hearing with which he hears, he seeing with which he sees, his hand with which he strikes and his foot with which he walks. Were he to ask [something] of Me, I would surely give it to him, and were he to ask Me for refuge, I would surely grant him it.” (al-Bukhaari, 6502).
