—Allah knows that inner dialogue even though it remains hidden from human beings. He, Mighty and Majestic, is All-Seeing: He perceives the stealthy crawl of a black ant upon a black rock in the darkest night—nothing escapes Him.
When you truly believe in Allah’s knowledge, power, hearing, and sight, that faith obliges you to watch over your conduct before your Lord: you should let Him hear only what pleases Him and do only what earns His good pleasure. If you speak, He hears you; if you act, Allah shows you to Himself. You therefore fear your Lord—lest He find you where He has forbidden, or miss you where He has commanded. You also fear letting Him hear anything He dislikes, or remaining silent about something He has ordered.
Likewise, once you believe in the perfection of Allah’s power, you will ask Him for whatever you desire, provided your supplication contains no transgression. Do not say, “That is too far-fetched” or “That is impossible,” for nothing is impossible under Allah’s power.
Consider Moses, peace be upon him: when he reached the Red Sea fleeing from Pharaoh and his troops, Allah commanded him to strike the sea with his staff. He struck it, and it split into twelve paths, the water between them rising like mountains. In an instant the seabed dried, and they walked across it as though traversing a desert that water had never touched—by the power of Allah.
It is also related that Saʿd ibn Abī Waqqāṣ, may Allah be pleased with him, during the conquest of Persia reached the Tigris—the well-known river in Iraq. The Persians crossed to the eastern bank, destroyed the bridges, and scuttled the boats so the Muslims could not follow. Saʿd consulted the Companions, and in the end they resolved to cross the river—and they did so.
