When it is said to them: "Do not make mischief on the Earth," they say: "Why? We only want to make peace." Beware, they are the ones that cause mischief but they do not realise. [Surah al-Baqarah (2):11-12]
The sign of a believer is that he understands the Religion and is constantly increasing his knowledge of certain matters and benefits and he is covetous of all that is good, as well as the gatherings wherein it is disseminated. The hypocrite, however, completely turns away. When the people talk in a gathering about matters to do with the Prayer or worship, it is to him as if they are speaking in a different language.
