Do sins committed at night in Ramadan affect the merits of fasting during the day?

Disobedience committed in Ramadan (definition), whether by day or night, is multiplied due to the sanctity of the time, and its sin increases. Even if it does not invalidate the fast, its danger is immense, and it may deprive one of obedience and humility. Sins are a cause of deprivation from obedience, repentance, and humility. Drinking alcohol is one of the gravest major sins, and it is even more prohibited in Ramadan. The fast of one who drinks it at night is valid if he abstains from things that break the fast with the intention of fasting.
