Day Questions

A person is a tenant of a property owned by a Shia Waqf organization. That person refuses to pay the agreed rent amount. Can such a person offer prayers in his house where the arrears are still outstanding and are such prayers valid?

If the said property is used by a person without paying its due rent then he is considered as a ghasib (usurper) and the prayer in such a place - if he is attentive of the fact that it is prohibited - is void.

Do Mujtahids differ in the laws of the prayer? For example one tells us to pray this way and another tells us to pray another way?

It is natural to have different derivations as people differ in their understanding of a single text, whereas the Mujtahids deal with numerous texts, plus the fact that as time passes further away from the time of the texts, fallacies and probabilities increase. From this, the mission of a Mujtahid becomes harder and his responsibility becomes greater in protecting the religion in a correct way and to the greatest possible extent. The oppressors and the liars throughout the times have made obstacles for us in obtaining the truths from the Imams (peace be upon them) which made the mission of the Mujtahids more difficult. Therefore some variations are to be expected.
