The ruling on a male doctor administering injections to women when no female doctor is available

From the Arab Republic of Egypt, the listener Salah ibn Muhammad ibn Adam al-Dardiri sent a somewhat lengthy message in which he says: Given that I am a student at the Faculty of Medicine at al-Azhar, and by virtue of my profession, I administer injections to Muslims for the sake of Allah the Exalted in my hometown, hoping for reward from Allah the Exalted. Many of these people are women whom it is not permissible for me to touch or shake hands with, knowing that there are no women to perform this task in my place, and circumstances compel me to do so, which forces me to touch what is not permissible for me to touch. I know that, praise be to Allah, I am a believer in Allah, and nothing but good comes to my mind. I recite the Qur'an while performing this task. I also require the presence of a male relative of hers with us, and if no male relative is present, I postpone performing the task until one of her relatives is available. I am very keen on this, if Allah wills. What is the ruling on this? And what is the ruling if I am fasting, whether the fast is obligatory or a recommended practice? May Allah reward you with good.
Answer: If the situation is as you described, then you are rewarded and there is no blame on you for administering the needle and injection to a woman or a man. You are to be thanked and rewarded. However, you should ensure that you are not alone with her, as you mentioned. It should be done in the presence of a man or a woman so that there is no seclusion, based on the saying of the Prophet (peace and blessings be upon him): If you administer it in the place where the need requires it, there is nothing wrong with that. Do not expose anything except the place of need only, and the rest should be covered. She should cover herself and observe modesty except for the place of need. And you, as much as possible, should lower your gaze from anything that may be visible except the place of need, without seclusion. There is no blame on you in this, praise be to Allah. Even if you are fasting, there is no blame on you. Yes.
The presenter: Whether the fast is obligatory or voluntary?
The Shaykh: Whether the fast is obligatory or voluntary, there is no blame on him. However, if she is fasting, or the man is fasting, it is better to postpone administering the injections to the night to avoid the scholarly disagreement. As for you, there is nothing on you. But if you postpone administering the injection to the man or woman until breaking the fast, if that is feasible, it is more cautious. Yes.
The presenter: May Allah reward you with good.
