On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (Sal Allahau Alaihi Wa Aalihi Wasallam) said: Allah (Mighty and Sublime be He) said:
Whosoever shows enmity to someone devoted to Me. I shall be at war with him. My servant draws not near to Me with anything more loved by Me than the religious duties I have enjoined upon him, and My servant continues to draw near to Me with supererogatory works so that I shall love him.
When I love him I am his hearing with which he hears, his seeing with which he sees, his hand with which he strikes and his foot with with 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. I do not hesitate about anything as much as I hesitate about [seizing] the soul of My faithful servant: he hates death and I hate hurting him.
