Does one break the fast if fasting is difficult for him due to a cold?

The questioner : We said that a cold does not permit breaking the fast, even though it is an illness. So he said: What about the one among you who is ill? Yes. And we said regarding the current: Your statement appeared a little while ago on a certain day, so how do you reconcile them?

The Shaykh : Reconciling them is easy, because we know that the intended meaning of the illness that permits breaking the fast is the one that makes fasting difficult for him. So if fasting is difficult for him, even if it is just a cold, he says: I break the fast.

The questioner : This is the operative cause, as I am saying.

The Shaykh : The operative cause, because the default for obligatory acts is that they are obligatory, and they are dropped by the opposite of this default.

The questioner : If there is a distinction, if there is hardship, he errs.

The Shaykh : I mean, with regard to fasting, yes.

The questioner : And it is obligatory.

The Shaykh : If it is difficult for him to fast with a cold, he breaks the fast; there is no problem.
