What is the ruling on someone who intentionally violated the sanctity of Ramadan?
If you mean that he broke his Sawm (Fast) on one or more days during Ramadan without a valid excuse and without engaging in sexual intercourse, then he has committed a major sin; and it is obligatory on him to make sincere Tawbah (repentance to Allah) and make up for the day on which he has broken his Sawm. However, if he broke his Sawm by engaging in sexual intercourse, it is obligatory on him to do what was mentioned above in addition to offering Kaffarah (expiation), which is to emancipate a believing slave. If this is not possible, he is to observe Sawm for two months consecutively. If he cannot do this, he must feed sixty Miskins (needy people), each with half a Sa` (1 Sa` = 3 kg. Approx.) of the staple food of the country.If you mean that he violated the sanctity of Ramadan by an act other than breaking his Sawm, such as by Ghibah (backbiting) or Namimah (tale-bearing), then he is to make Tawbah and Istighfar (seeking forgiveness from Allah) and his Sawm will be valid.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
