Surah Al-Baqarah, ayah 103

وَلَوۡ أَنَّهُمۡ ءَامَنُواْ وَٱتَّقَوۡاْ لَمَثُوبَةٞ مِّنۡ عِندِ ٱللَّهِ خَيۡرٞۚ لَّوۡ كَانُواْ يَعۡلَمُونَ ١٠٣

Walaw annahum āmanū wattaqaw lamathūbatum min 'indillāhi khayrul law kānū ya'lamūn

And if they had believed and feared Allāh, then the reward from Allāh would have been [far] better, if they only knew.
