Purification of Masjid is Wajib Purifying the Masjid immediately is Wajib, such that it should not be generally considered as wilful delay or heedlessness. Immediately means that if there is some time for the prayer it should be purified before prayers. It should also be clear that purifying the Masjid is incumbent not only on the person who has polluted it, but it is a Wajib al-Kifai on all Muslims. It is Wajib to bear the expenses even if it is a costly matter.
If one cannot bear the cost alone it is incumbent on him to ask help from others. Staying in the Mosque in a state of Janabat, Haiz or Nifas A Junub person, a woman in haiz or Nifas is not permitted to stay in a mosque.
Thus the Holy Qur’an says: “Nor when you are under an obligation to perform a bath — unless (you are) travelling on the road — until you have washed yourselves.” (Surah an-Nisā’ 4: 43) In other words a Junub person is allowed to pass through a mosque from one door and out of another. He cannot come out from the same door nor leave anything inside the mosque.
However, in the case of Masjidul Harām, Masjidun Nabi and Masjidul Aqsa the Junub persons and haiz and Nifas women cannot even pass through them. Recommended Actions Lighting a lamp in Masjid, keeping it absolutely clean and pure, entering it with the right foot forward and leaving it with the left foot first are all recommended (Mustahab) acts. Before entering we must ensure that our shoes are not najis, lest the Masjid becomes najis due to it.
Enter the Masjid in a state of ritual purification (Ghusl and Wuzu). Wear the best dress, apply perfume and pray two rakat prayers of saluting the mosque. Detestable (Makrūh) Acts assing through a mosque is Makrūh without reciting at least two rakats of prayers. We must not throw nasal discharge and sputum in the mosque.
Also makrūh are the following acts: sleeping in the mosque, raising ones voice except in Azan (call for prayer), announcing lost property loudly, or asking something from a person, reciting poetry that does not contain any moral lessons. Discussing worldly matters and business transactions are makrūh in a Masjid. We must not go to the mosque after eating onion, garlic or anything that creates a foul breath. We must also avoid taking young children and insane persons inside the mosque.
Different Grades of Mosques The most sacred and honourable mosque is Masjidul Harām. A prayer inside this Masjid equals one hundred thousand prayers in ordinary Masjids.
