Your Lord drives the ship so you can seek His bounty.
Mercy in ordinary travel and trade
After the warnings about Shaytan, the surah turns to Allah's kindness. Ibn Kathir says He made ships easy to use for trade between one region and another. He does this out of His grace and mercy.
The cargo ship that brought your phone. The bus you take to work. The delivery van with your groceries. A whole chain of travel brings your daily bread. Every trip you take for your living is held up by His mercy.
Getting to work and earning a living is just logistics.
Every journey that brings me provision is a mercy from my Lord.
Say the travel dua, subhanalladhi sakhkhara lana hadha, on your next commute.
