And He has subjected to you whatever is in the heavens and whatever is on the earth – all from Him. Indeed in that are signs for a people who give thought. (Quran 45:13).
Is one who is devoutly obedient during periods of the night, prostrating and standing [in prayer], fearing the Hereafter and hoping for the mercy of his Lord, [like one who does not]? Say, “Are those who know equal to those who do not know?” Only they will remember [who are] people of understanding. (Quran 39:9).
We will show them Our signs in the universe and within themselves until it becomes clear to them that this [Quran] is the truth. Is it not enough that your Lord is a Witness over all things? (Quran 41:53).
Allah [Himself] is a Witness that there is no god [worthy of worship] except Him—and so are the angels and people of knowledge. He is the Maintainer of justice. There is no god [worthy of worship] except Him—the Almighty, All-Wise.. (Quran 3:18).
Read, [O Prophet], in the Name of your Lord Who created. Created humans from a clinging clot. Read! And your Lord is the Most Generous. Who taught by the pen. Taught humanity what they knew not. (Quran 96:1-6).
[However], it is not necessary for the believers to march forth all at once. Only a party from each group should march forth, leaving the rest to gain religious knowledge then enlighten their people when they return to them, so that they [too] may beware [of evil]. (Quran 9:122).
As for those who struggle in Our cause, We will surely guide them along Our Way. And Allah is certainly with the good-doers. (Quran 29:69).
O believers! When you are told to make room in gatherings, then do so. Allah will make room for you [in His grace]. And if you are told to rise, then do so. Allah will elevate those of you who are faithful, and [raise] those gifted with knowledge in rank. And Allah is All-Aware of what you do. (Quran 58:11).
