The Command for the One Who Abandons Prayer to Fast and the Ruling on His Fasting

Question:
Is the one who abandons prayer commanded to fast, and if he does fast, does he have any share in his fasting?

Answer:
The one who abandons the prayer is a disbeliever, and a disbeliever has no fasting. Even if he is held accountable for it on the Day of Resurrection and excused for it, his disbelief is a serious matter in terms of punishment according to the Shari'ah. However, he is not required to do it in this world unless he enters Islam. For this reason, when the Prophet (peace and blessings be upon him) sent Mu'adh to Yemen, he ordered him to first command them to tawhid (the oneness of Allah), or to the oneness of the Lord, then to the prayer, then to the zakah. A disbeliever is first commanded to bear witness to the two testimonies, and once he becomes a Muslim, he is commanded to perform the prayer, the zakah, fasting, and other obligations. The one who abandons the prayer has committed an act of disbelief and has incurred a burden from what has befallen Islam. The Prophet (peace and blessings be upon him) said: , and he (peace and blessings be upon him) said: "There is no excuse" and he has committed it. And he (peace and blessings be upon him) said: "Whoever abandons the 'Asr prayer," which is a general hadith, has no fasting or anything else until he turns to Allah, inclines toward Him, and renews his Islam with all that is obligatory upon him.
