Does fasting for the obligatory fast only apply to the hadith regarding the entry of the fasters through the Gate of Rayyan in Paradise?

Question:
Does the hadith that mentions a gate in Paradise called the Gate of Rayyan, through which only the fasters enter, apply only to the obligatory fast?

Answer:
Yes, it is mentioned in the hadith Paradise has gates.
Paradise has eight gates. The statement of the Messenger of Allah (peace and blessings be upon him), "They will be called to the eight gates of Paradise, and they will enter through whichever they wish," indicates that Paradise has eight gates. And Allah (Exalted and Majestic is He) says: Paradise has gates; this is in the Qur'an. The fact that there are eight is in the Sunnah, in the Sunnah of the Messenger of Allah (peace and blessings be upon him). Each of these gates is designated for a specific deed: the Gate of Charity, the Gate of Prayer, the Gate of Fasting, the Gate of Jihad. Each gate is specific to certain righteous deeds, including the Gate of Rayyan, which is designated for the fasters. The opposing view, meaning disobedience that is contrary to the ruling, is not a forbidden sin, but rather a sin that is contrary to what is better and more preferable. Yes. And the intent of the Messenger of Allah (peace and blessings be upon him) in that was deterrence. Labeling this as a sin is a matter of deterrence, and it does not mean that it is forbidden, but rather that it is contrary to what is better and more preferable.
