If He wishes, He can make the wind still, and then they will become motionless on the sea’s surface. Indeed, in this are signs for every patient and grateful one.
Even though ships today do not depend on wind as in earlier times, if the wind became still, everything—including ships—would become motionless as machineries fail to work. Therefore, the believer who utilizes the Insight—Adhikr—fulfills the aim of life by identifying Allah, who, as part of His favors, has made the structure of water and air suitable for ships to sail smoothly. But the Fujjar, who are the Mujrim and wrongdoers as told in verses 7:40-41, by hiding and rejecting Adhikr are serving Satan and have forgotten the aim of life; thus, they are into Hellfire. See explanation 31:31-32; 48:6 and 98:6.
