Al-Ma'idah 5:93

Laysa AAala allatheena amanoowaAAamiloo assalihati junahun feemataAAimoo itha ma ittaqaw waamanoowaAAamiloo assalihati thumma ittaqaw waamanoothumma ittaqaw waahsanoo wallahu yuhibbualmuhsineen

There is not upon those who believe and do righteousness [any] blame concerning what they have eaten [in the past] if they [now] fear Allāh and believe and do righteous deeds, and then fear Allāh and believe, and then fear Allāh and do good; and Allāh loves the doers of good.

There is no sin, for those who believe and do good deeds, in what they might have partaken earlier, if they fear Allah, and believe, and do good deeds; and again fear Allah, and believe, and still again fear Allah and do good deeds. Allah loves those who are good in their deeds.
