"O my Lord! Make me perfect in knowledge and conduct and include me among those whom You have rewarded with Your nearness." - Qur’ān (ash-Shu‘arā’, the Poets) 26:83   [Where Hazrat Ibrāhīm(عليه السلام) is praying to Allah - Src: Ch3 of Beseeching for Help, Tahir-ul-Qadri]

Allah Most High says: "He who is hostile to a friend of Mine I declare war against. My slave approaches Me with nothing more beloved to Me than what I have made obligatory upon him, and My slave keeps drawing nearer to Me with voluntary works until I love him. And when I love him, I am his hearing with which he hears, his sight with which he sees, his hand with which he seizes, and his foot with which he walks. If he asks me, I will surely give to him, and if he seeks refuge in Me, I will surely protect him"

(Sahih Bukhari - Fath al-Bari, 11.340 41, hadith 6502) [src: suhba.org]
