Salams. I am going to join after 2 months apex level institute of country. I wish to continue ?namaz? timely for which I have talk to Director who pose before me some situation and asked me that if you tell me proper answer to it then I will allow you to pray otherwise you have to stop it while on duty or you will not be allowed to join institute. He asked me how will you pray without interfering your duty when you are-1. in OPD, and hundreds of patients are waiting for their turns2. in ?casualty?; emergency cases may come any time and suppose there are not much staff in spare3. in OT, doing major surgery likely to take >6 hours4. in ?ward? as its incharge and HOD comes to take round of ward. You should be there to tell him about all the patients, he is not going to wait for you, he has to take round of all wards.5. in ?Labor Room?. Please answer me quickly; I do not want to loss ?neither namaz nor such institute. Also, tell me-can I remove cap and stop growing beard, as Director has told me that it is not essential (farz) and for lay man it is OK but such appearance does not suit a doctor, also it may adversely affect my future because patient, specially female and non-Muslim, will avoid me.
