Detestable (Makrūh) Acts
Passing 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.
