Tafsir
If Allah wished to make the wind that moves them still He would have done so, and they will remain fixed on the ocean motionless. In that which has been mentioned about the creation of ships and the subjugation of the winds there are clear signs of Allah’s power for every person who is patient in difficulty and trials, and who is grateful for Allah’s favours to him.
