رَّبُّكُمُ ٱلَّذِى يُزْجِى لَكُمُ ٱلْفُلْكَ فِى ٱلْبَحْرِ لِتَبْتَغُوا۟ مِن فَضْلِهِۦٓ ۚ إِنَّهُۥ كَانَ بِكُمْ رَحِيمًا
Translations
It is your Lord who drives the ship for you through the sea that you may seek of His bounty. Indeed, He is ever, to you, Merciful.Votre Seigneur est Celui qui fait voguer le vaisseau pour vous en mer, afin que vous alliez à la recherche de quelque grâce de Sa part; Certes Il est Miséricordieux envers vous,Tafsir
Your Lord - O people - is the one who makes the ships sail for you in the sea, hoping to seek your sustenance through the profits from trade and the like. He is Merciful to you as He facilitated these means for you.
Read Ibn Kathir (Ibn Kathir (abridged, English))
Your Lord is He Who drives the ship for you through the sea, in order that you may seek of His bounty. Truly, He is ever Most Merciful towards you (66)
Ships are a Sign of the Mercy of Allah
Allah tells us of His kindness towards His servants by subjugating for them ships on the sea. He makes it easy for them to use ships to serve their interests, seeking His bounty through trade between one region and another. He says:
إِنَّهُ كَانَ بِكُمْ رَحِيمًا
(Truly, He is ever Most Merciful towards you.) meaning, He does this for you out of His grace and mercy towards you.
