And a proclamation from Allah and His messenger to all men on the day of the Greater Pilgrimage that Allah is free from obligation to the idolaters, and (so is) His messenger. So, if ye repent, it will be better for you; but if ye are averse, then know that ye cannot escape Allah. Give tidings (O Muhammad) of a painful doom to those who disbelieve,
Surah At-Tawba(9:3)

Fasting
Chapter: Fasting is obligatory in (the month of) Ramadan
Narrated `Aisha:
(The tribe of) Quraish used to fast on the day of Ashura' in the Pre-Islamic period, and then Allah's Apostle ordered (Muslims) to fast on it till the fasting in the month of Ramadan was prescribed; whereupon the Prophet (ﷺ) said, "He who wants to fast (on 'Ashura') may fast, and he who does not want to fast may not fast."
