Quran 3:29 from Surah Aal-i-Imraan on Divine Marvels.
قُلۡ إِن تُخۡفُواْ مَا فِي صُدُورِكُمۡ أَوۡ تُبۡدُوهُ يَعۡلَمۡهُ ٱللَّهُۗ وَيَعۡلَمُ مَا فِي ٱلسَّمَٰوَٰتِ وَمَا فِي ٱلۡأَرۡضِۗ وَٱللَّهُ عَلَىٰ كُلِّ شَيۡءٖ قَدِيرٞ
English translation: Say Whether you conceal what (is) in your breasts or you disclose it knows it Allah And He knows what (is) in the heavens and what (is) in the earth And Allah (is) on every thing All-Powerful
Transliteration: qul in tukh'fu ma fi sudurikum aw tub'duhu ya'lamhu al-lahu waya'lamu ma fi al-samawati wama fi al-ardi wal-lahu ala kulli shayin qadirun
