Is it permissible to combine the intention of fasting Monday, the white days, and the six days of Shawwal?

Question : May Allah reward you. Is it possible to combine two intentions, for example, the intention of fasting on Monday or the white days with the six days of Shawwal?

Answer : Yes. If fasting the white days coincides with Monday or Thursday, the person is credited with two rewards: the reward for fasting on Thursday and the reward for fasting the white days. Likewise, if the six days of Ramadan coincide with Monday and Thursday, he is credited with fasting the six days and fasting on Monday and Thursday, because it is true that he fasted on Monday or fasted on Thursday. Just as a person who enters the mosque and prays the rawatib (the regular voluntary prayers attached to the obligatory ones), such as the rawatib of the midday prayer or the dawn prayer, receives two rewards: the reward for the voluntary prayer and the reward for greeting the mosque.
