Day Questions

I travelled to another city 150km away, and I could not offer the Zuhr and Asr prayers. I returned that night, and I wish to perform the Qadha prayers. Should they be offered shortened, as I was travelling then, or should they be offered in full, as I am actually offering them at home?

It is forbidden to fail to pray on time, even if you are travelling. You must try to perform the prayers by any possible means. But if you did not, then you will make them up later shortened, even if you are at home now.

If I go to a mosque or a shrine of an Imam and find a scholar whom I do not know leading prayers in front of a very large group of people, none of whom I know, is it permissible for me to pray with them in congregation? Or is it necessary for me to first get to know the scholar, spend time with him and so on to ascertain that he is adil?

The Adalah of the imam must be considered before one offers congregational prayer. It can be determined by knowledge and certainty that originates from dealing with him or from other ways of reaching such knowledge, testimony of two Adil witnesses and by good apparent behavior. Having a big crowd that offer the prayer behind a person is not sufficient.

I am a married woman, is there any form of birth control that I am permitted to use in order to prevent pregnancy?

There are two scenarios, Firstly: if childbirth will cause bodily harm, it is permissible to disable the reproductive system even if this is permanent in order to alleviate the harm. Secondly: it is permissible to temporarily disable the reproductive system, even if childbirth does not cause any bodily harm. However, if this involves prohibited exposing or touching of the body then it is not permissible except if there is a conventional necessity that requires this.
