Does a physician commit a sin if he is called to treat a patient and he makes an excuse?

The questioner : My Shaykh says here: If a physician is called to a patient to treat him in his home, and he makes an excuse, does he commit a sin? Knowing that this may be in a village where there is disturbance for the physician day and night? And for simple medical conditions, he mentions his situation, saying he is in a village and may be called to a neighboring village, so traveling to that village involves disturbances from some people, and the illness is not that serious illness.

The Shaykh : He can live there.

The questioner : Yes, so does he commit a sin in making an excuse?

The Shaykh: No.

The questioner : He does not commit a sin.
