Yahya ibn Sa'id heard from Sa'id ibn al-Musayyib, he was asked about making up missed fasts of Ramadan, so Sa'id said: In my view, it is good to make up the missed fasts of Ramadan consecutively.

Imam Malik, may Allah have mercy on him, said: Whoever makes up the missed fasts of Ramadan separately, it is not obligatory for him to repeat them, rather the making up will suffice, but in my view, it is better to make them up consecutively.

Imam Malik, may Allah have mercy on him, said: Whoever eats or drinks forgetfully in Ramadan, or in any other obligatory fast, then he must make up that fast.
