وَمِنْ ءَايَٰتِهِۦٓ أَن يُرْسِلَ ٱلرِّيَاحَ مُبَشِّرَٰتٍۢ وَلِيُذِيقَكُم مِّن رَّحْمَتِهِۦ وَلِتَجْرِىَ ٱلْفُلْكُ بِأَمْرِهِۦ وَلِتَبْتَغُوا۟ مِن فَضْلِهِۦ وَلَعَلَّكُمْ تَشْكُرُونَ
And of His signs is this: He sendeth herald winds to make you taste His mercy, and that the ships may sail at His command, and that ye may seek his favour, and that haply ye may be thankful.
