Entering the mosque without wudu' and the greeting of the mosque

Question:
If I want to enter the mosque to attend a lesson or a lecture, and I have not performed wudu', and I cannot find water, do I not perform wudu' and pray the greeting of the mosque, or do I enter without praying the greeting of the mosque, or do I speak about attending the mosque?

Answer:
First, it is not the case that there is no water in a town or around it; this is a conceivable scenario, but a mosque is not established except in a town where there is water or farms, and water is available, though it may be needed. Second, the greeting of the mosque is not obligatory. If you enter and sit, there is no blame on you, because it is a recommended practice (sunnah), and one who performs a recommended practice is not rewarded, nor is one punished for leaving it, but it is a confirmed recommended practice, and one should not neglect it when it is possible. Other than that, if Allah wills, it will not happen that there is a mosque in a town without the dispensation (rukhsah) being available. Yes.
