Will a doer of good who performs some of the obligatory prayers and omits others enter Paradise?

Abandoning prayer is a serious matter that can lead to disbelief (kufr), which nullifies all good deeds. It is not permissible to abandon prayer, not even a single one. Whoever abandons prayer relying on other good deeds is deluded. Allah Almighty has warned those who delay prayer beyond its prescribed time, so what then of those who abandon it entirely? As for one who dies before repenting and has not associated partners with Allah, their matter is subject to Allah's will: He may punish them if He wills, or forgive them if He wills.
