وَإِذَا مَسَّكُمُ ٱلضُّرُّ فِى ٱلْبَحْرِ ضَلَّ مَن تَدْعُونَ إِلَّآ إِيَّاهُ ۖ فَلَمَّا نَجَّىٰكُمْ إِلَى ٱلْبَرِّ أَعْرَضْتُمْ ۚ وَكَانَ ٱلْإِنسَٰنُ كَفُورًا
And when harm toucheth you upon the sea, all unto whom ye cry (for succour) fail save Him (alone), but when He bringeth you safe to land, ye turn away, for man was ever thankless.
Surah Al-Israa(17:67)
