The questioner : Also, the question is valid because some Muslims, especially outside this country or those who come to it, consider that if a worship is missed, it is dropped. So if the prayer is missed from its time, it is not performed, and if Ramadan is missed or part of Ramadan is missed, they do not fast. What is the ruling on fasting in Ramadan?
The Shaykh : Yes, or… or… We have previously established a rule. We said that if a person performs a time-bound act of worship outside its designated time without an excuse, it is never valid from him, even if he repeats it a thousand times. He must repent, and repentance is sufficient. However, if he left off fasting due to an excuse, such as illness, travel, or something else, he must make it up, as Allah the Exalted said:[Al-Baqarah 2:185].

and whoever is ill or on a journey - then an equal number of other days
وَمَن كَانَ مَرِيضًا أَوْ عَلَىٰ سَفَرٍ فَعِدَّةٌ مِّنْ أَيَّامٍ أُخَرَ
