Surah Al-Isra' (The Night Journey), Verse 67

وَاِذَا مَسَّكُمُ الضُّرُّ فِی الْبَحْرِ ضَلَّ مَنْ تَدْعُوْنَ اِلَّاۤ اِیَّاهُ فَلَمَّا نَجّٰىكُمْ اِلَی الْبَرِّ اَعْرَضْتُمْ وَكَانَ الْاِنْسَانُ كَفُوْرًا ۟

Wa izaa massakumuddurru fil bahri dalla man tad'oona illaaa iyyaahu falammaa najjaakum ilal barri a'radtum; wa kaanal insaanu kafooraa

“When distress seizes you at sea, those that ye call upon - besides Himself - leave you in the lurch! but when He brings you back safe to land, ye turn away (from Him). Most ungrateful is man!”

Quran 17:67 (Yusuf Ali Translation)
