Day Questions

Can a supplication be recited in the ruku or prostration of an obligatory or recommended prayer?

It is permissible to recite any supplication. It has been recommended in some narrations to recite the salawat after the obligatory recitation of the prostration and the bowing.

Is it permissible for a believer to propagate the religion to non-Muslims, but of course, not in a forceful or annoying manner?

It is recommended to spread the truth, and Almighty Allah will give great rewards to those who do such noble acts. It is reported that the Prophet said to Imam Ali (peace be upon them): “If Allah, through you, guides a single person, it is better for you than all what the Sun shines on.”

Does ghusl have to be performed when one touches someone else in the state of janabah without being in the state of janabah himself?

No, touching somebody in the state of janabah is not a cause for janabah. One has to perform ghusl of janabah due to either sexual intercourse or release of semen, and not for any other reason.
