An Nawawi's Forty Hadith

The messenger of Allah said: "Allah the Almighty has said: 'Who soever shows enmity to a friend of Mine, I shall be at war with him. My servant does not draw near to Me with anything more loved by Me than the religious duties I have imposed 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 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.'"
