Quran 29:65 from Surah Al-Ankaboot on Divine Marvels.
فَإِذَا رَكِبُواْ فِي ٱلۡفُلۡكِ دَعَوُاْ ٱللَّهَ مُخۡلِصِينَ لَهُ ٱلدِّينَ فَلَمَّا نَجَّىٰهُمۡ إِلَى ٱلۡبَرِّ إِذَا هُمۡ يُشۡرِكُونَ
English translation: And when they embark [in] the ship they call Allah (being) sincere to Him (in) the religion But when He delivers them to the land behold they associate partners (with Him)
Transliteration: fa-idha rakibu fi al-ful'ki da'awu al-laha mukh'lisina lahu al-dina falamma najjahum ila al-bari idha hum yush'rikuna
