Luqman Ayah 31

أَلَمْ تَرَ أَنَّ ٱلْفُلْكَ تَجْرِى فِى ٱلْبَحْرِ بِنِعْمَتِ ٱللَّهِ لِيُرِيَكُم مِّنْ ءَايَـٰتِهِۦٓ‌ۚ إِنَّ فِى ذَٲلِكَ لَأَيَـٰتٍ لِّكُلِّ صَبَّارٍ شَكُورٍ ٣١ Do you not see that the ships sail ?smoothly? through the sea by the grace of Allah so that He may show you some of His signs? Surely in this are signs for whoever is steadfast, grateful.
