Al-An'am 6:63

قُلْ مَن يُنَجِّيكُم مِّن ظُلُمَٰتِ ٱلْبَرِّ وَٱلْبَحْرِ تَدْعُونَهُۥ تَضَرُّعًۭا وَخُفْيَةًۭ لَّئِنْ أَنجَىٰنَا مِنْ هَٰذِهِۦ لَنَكُونَنَّ مِنَ ٱلشَّٰكِرِينَ

Say: "Who is it that delivereth you from the dark recesses of land and sea, when ye call upon Him in humility and silent terror: 'If He only delivers us from these (dangers), (we vow) we shall truly show our gratitude'?"
