Hûd
[26:123] ‘Ãd disbelieved the messengers. [26:124] Their brother Hûd said to them, “Would you not be righteous? [26:125] “I am an honest messenger to you. [26:126] “You shall reverence GOD, and obey me. [26:127] “I do not ask you for any wage; my wage comes from the Lord of the universe. [26:128] “You build on every hill a mansion for vanity’s sake. [26:129] “You set up buildings as if you last forever. [26:130] “And when you strike, you strike mercilessly. [26:131] “You shall reverence GOD and obey me. [26:132] “Reverence the One who provided you with all the things you know. [26:133] “He provided you with livestock and children. [26:134] “And gardens and springs. [26:135] “I fear for you the retribution of an awesome day.” [26:136] They said, “It is the same whether you preach, or not preach. [26:137] “That affliction was limited to our ancestors. [26:138] “No retribution will ever befall us.” [26:139] They thus disbelieved and, consequently, we annihilated them. This should be a lesson, but most people are not believers. [26:140] Most assuredly, your Lord is the Almighty, Most Merciful.
Divine Revelation: The Source of All Knowledge
[17:85] They ask you about the revelation. Say, “The revelation comes from my Lord. The knowledge given to you is minute.” [17:86] If we will, we can take back what we revealed to you, then you will find no protector against us.
Example of David
[4:94] O you who believe, if you strike in the cause of GOD, you shall be absolutely sure. Do not say to one who offers you peace, “You are not a believer,” seeking the spoils of this world. For GOD possesses infinite spoils. Remember that you used to be like them, and GOD blessed you. Therefore, you shall be absolutely sure (before you strike). GOD is fully Cognizant of everything you do.
