To be moderate necessitates behavior which remains within the boundaries of the Qur’an: that is, doing what is lawful and avoiding what is forbidden. This requires a well-balanced outlook. When believers become involved with profane societies, they should never act as their members do. Believers should always obey what has been decreed by the Qur’an, remaining consistently temperate in their approach.
However, this is definitely not something to be done just when the believers are in a society other than their own; they should also be of the same temper among the believers. There are also some situations when special attention should be paid to propriety:
“O you who believe! Do not raise your voices above the voice of the Prophet, nor speak aloud to him in talk as you may speak aloud to one another, lest your deeds become vain and you perceive not.” (Surat al-Hujraat, 49:2)
Moreover, the risk of behaving immoderately may even occur in doing something which is legitimate. This is because not every manner fits every situation. A way of speaking or behaving may sometimes be “unsuitable” or “improper” although it is not forbidden. That is why the believer should avoid being sharp-tongued or indulging in any other extremes of behaviour. He should try to develop his personality so as not to become nervous or very excited, and should never lose his temper or misbehave. The Qur’an expresses disapproval of conduct which is not consistently marked by moderation:
“No misfortune befalls on the earth or in yourselves but is inscribed in the Book of Decrees, before We bring it into existence. Verily, that is easy for Allah. In order that you may not despair over matters that pass you by, nor exult over favours bestowed upon you. For Allah does not love any vainglorious boaster.” (Surat al-Hadid, 57:22-23)
