﴿ لَيْسَ عَلَى ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ جُنَاحٌۭ فِيمَا طَعِمُوٓا۟ إِذَا مَا ٱتَّقَوا۟ وَّءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ ثُمَّ ٱتَّقَوا۟ وَّءَامَنُوا۟ ثُمَّ ٱتَّقَوا۟ وَّأَحْسَنُوا۟ ۗ وَٱللَّهُ يُحِبُّ ٱلْمُحْسِنِينَ ﴾

“Those who have attained to faith and do righteous deeds incur no sin by partaking of whatever they may, so long as they are conscious of God and [truly] believe and do righteous deeds, and continue to be conscious of God and to believe, and grow ever more conscious of God, and persevere in doing good: for God loves the doers of good.”

Those who believe and perform righteous deeds are not at fault in what they may have consumed of wine and indulged in of gambling before the prohibition so long as they fear the forbidden things and believed and performed righteous deeds and then were God-fearing and believed and then adhered to fear of God and belief and then were God-fearing and virtuous in deeds; God loves the virtuous meaning that He will reward them.
