10-Surah Yunus ( Jonah ) 22
It is He who enables you to travel on land and sea until, when you are in ships and they sail with them by a good wind and they rejoice therein, there comes a storm wind and the waves come upon them from everywhere and they assume that they are surrounded, supplicating Allah, sincere to Him in religion, ‘ If You should save us from this, we will surely be among the thankful.’
هُوَ الَّذِي يُسَيِّرُكُمْ فِي الْبَرِّ وَالْبَحْرِ ۖ حَتَّىٰ إِذَا كُنتُمْ فِي الْفُلْكِ وَجَرَيْنَ بِهِم بِرِيحٍ طَيِّبَةٍ وَفَرِحُوا بِهَا جَاءَتْهَا رِيحٌ عَاصِفٌ وَجَاءَهُمُ الْمَوْجُ مِن كُلِّ مَكَانٍ وَظَنُّوا أَنَّهُمْ أُحِيطَ بِهِمْ ۙ دَعَوُا اللَّهَ مُخْلِصِينَ لَهُ الدِّينَ لَئِنْ أَنجَيْتَنَا مِنْ هَٰذِهِ لَنَكُونَنَّ مِنَ الشَّاكِرِينَ
Quran's Tafhim ( explanation)
*31). This particular 'sign' which testifies to the truth of belief in the One True God is innate in human nature and hence can be witnessed by all. However, as long as the means of self-indulgence are plentiful, man tends to forget God and exults in his worldly enjoyment. But as soon as the means which have led him to his worldly efflorescence are gone, even the most die-hard polytheists and atheists begin to appreciate this innate sign testifying that there indeed is a God Who has His firm grip over the universe, and that it is the One True God alone Who is all-powerful and Who holds sway over all that exists.
