Thinking deeply about the signs leading to faith is not left up to the person's will; rather, the Qur'an commands us to do so. For that reason, thinking about these signs that encompass the universe is a constant religious observance for believers.
Thanks to the signs leading to faith, which enable believers to feel His existence at every moment and in a most powerful manner, they can better understand His names and their superior nature. Once this deeper understanding is established, they try to draw ever close to Him. Due to the deep understanding stemming from these signs, and because they have seen the infinite nature of God's knowledge and might, they live with a greatly increased fear [and awareness] of Him and with a desire and longing to attain His mercy, compassion, and Paradise. Eventually, if He wills, they depart from this world, in which they appreciated God and hoped for His mercy, and go to live in the palaces of Paradise and the rivers flowing beneath them. One of the verses that inform believers of this good news of Paradise reads as follows:
Whereas those who believe and do right actions, such people are the Companions of the Garden, remaining in it timelessly, forever. (Qur'an, 2:82)
But unbelievers, due to their lack of consciousness and knowledge, heedlessly turn their backs on the manifest proofs of God's existence. The Qur'an reveals the end awaiting them:
But as for those who do not believe and deny Our Signs, they are the Companions of the Fire, remaining in it timelessly, forever. What an evil destination! (Qur'an, 64:10)
In the light of these verses, those who fear Hell and hope for Paradise, with its infinite joys and in which everything their hearts could desire is created in the most perfect and flawless manner, must work to attain our Lord's mercy, friendship, and love by coming to know Him better. To that end, they must acquire a greater knowledge and understanding of His names by pondering deeply on the signs leading to faith. In addition, they must explain these signs to others and become a means whereby they increase their faith. This responsibility is incumbent upon all believers.
They said: "Glory be to You! We have no knowledge except what You have taught us. You are the All-Knowing, the All-Wise." (Qur'an, 2:32)
He cast firmly embedded mountains on the ground so that it would not move under you, and rivers and pathways so that, hopefully, you would be guided.
