The ruling on one who abandons fasting for several years

Question:
The questioner says: I have fasted for several years, specifically three years without an excuse, and Allah guided me. What should I do? Fasting is difficult for me.

Answer:
If he abandoned fasting but was praying and did not abandon the prayer, it is obligatory for him to make up the fasts; it is obligatory for him to make up three months. However, if he abandoned the prayer along with the fasting, and he intentionally abandoned the prayer, then it is obligatory for him to repent and enter Islam anew, because one who intentionally abandons the prayer is a disbeliever, and his fasting is not valid even if he fasts, as long as he intentionally abandons the prayer. So he must repent to Allah and commit to performing the pillars of Islam anew. Yes. As for if, during the period he abandoned fasting, he did not abandon the prayer, this is a Muslim, a Muslim who abandoned fasting, so it is obligatory for him to make it up?
