Q:

1. Is it permissible to send seasonal greeting cards to non-Muslims at the time of Christmas so long as there are no religious symbols on them and without the intention of celebrating or supporting Christmas?
2. Can the following from al-ashbaah be used as a justification for sending seasonal greeting cards at Christmas time?

In al-ashbaah it states that if a person says regarding a non Muslim: "May Allah let his kingdom last for a long time" and his intention is that he may be given hidayat in future, or that the Muslims could benefit through his contributions of jizyah etc, then this is permitted. 

Q: While leading the salaah, I had a feeling that mazi may have been discharged, but was not sure. When I returned home, I found a slight wetness
at the tip of my private area, and it was only when I began to clean it that the mazi began come out. Now I am uncertain if it remained in the passage 
during salaah and began to come out as a result of walking, or if any came out during salaah. Firstly, will it be necessary for the congregation to repeat the salaah? Secondly, is this common, or is it a medical issue?
