Surah Al-Ankabut (The Spider), Verse 65

فَاِذَا رَكِبُوْا فِی الْفُلْكِ دَعَوُا اللّٰهَ مُخْلِصِیْنَ لَهُ الدِّیْنَ فَلَمَّا نَجّٰىهُمْ اِلَی الْبَرِّ اِذَا هُمْ یُشْرِكُوْنَ ۟

Fa-izaa rakiboo fil fulki da'awul laaha mukhliseena lahud deena falammaa najjaa hum ilal barri izaa hum yushrikoon

“Now, if they embark on a boat, they call on Allah, making their devotion sincerely (and exclusively) to Him; but when He has delivered them safely to (dry) land, behold, they give a share (of their worship to others)!-”
