What is the ruling on fasting during jihad?

Question:
It is said that whoever fasts a day in the cause of Allah, the one who fasts when the two lines meet?

Answer:
No, it is not recommended for him to fast; in jihad, no, it is not recommended. Because when the Prophet (peace and blessings be upon him) approached Makkah in the Year of the Conquest, he ordered them to break their fast and said: When it reached him that some of them were fasting, he said: At times of need, they should not fast; because breaking the fast is stronger, in the cause of Allah, meaning in obedience to Allah and seeking His pleasure, not for showing off or seeking reputation.
Q: And what is the stronger position in your view?
The Shaykh: This is the best that has been said regarding the hadith.
Q: If he is in a state of waiting (muraqabah)?
The Shaykh: If he is in a state of waiting, or at a time when fasting does not weaken him, and there is no engagement in combat; there is nothing wrong with it, and it has merit.
Q: Does this include the obligatory and the voluntary?
The Shaykh: No, what is meant here is the voluntary.
