"I will declare war against him..."

Narrated Abu Hurairah RadiAllaahu anhu: Allaah's Messenger SalAllaahu alaihe was sallam said, "Allaah 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 and doing extra deeds besides what is obligatory) until I love him, then 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 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.'" [Sahih al Bukhari, hadeeth #6502, The Book of AR-RIQAQ (Softening of the Hearts)]
