Al-Ma'idah' - 5:93

لَيْسَ عَلَى الَّذِينَ آمَنُواْ وَعَمِلُواْ الصَّالِحَاتِ جُنَاحٌ فِيمَا طَعِمُواْ إِذَا مَا اتَّقَواْ وَّآمَنُواْ وَعَمِلُواْ الصَّالِحَاتِ ثُمَّ اتَّقَواْ وَّآمَنُواْ ثُمَّ اتَّقَواْ وَّأَحْسَنُواْ وَاللّهُ يُحِبُّ الْمُحْسِنِينَ
[5:93]
On those who believe and do good there is no blame for what they eat, when they are careful (of their duty) and believe and do good deeds, then they are careful (of their duty) and believe, then they are careful (of their duty) and do good (to others), and Allah loves those who do good (to others).
On those who believe and do deeds of righteousness there is no blame for what they ate (in the past), when they guard themselves from evil, and believe, and do deeds of righteousness,- (or) again, guard themselves from evil and believe,- (or) again, guard themselves from evil and do good. For Allah loveth those who do good.
There shall be no sin (imputed) unto those who believe and do good works for what they may have eaten (in the past). So be mindful of your duty (to Allah), and believe, and do good works; and again: be mindful of your duty, and believe; and once again: be mindful of your duty, and do right. Allah loveth the good.
