What does modesty signify in believers?

Modesty is mentioned in the Qur’an as an important attribute of believers. Allah, in His verses, commands believers to be modest. It is also related in Qur’anic verses that Allah does not love those who are haughty and boastful. Believers are those who are aware of the fact that Allah is the Creator and the only Lord of everything, and that it is He Who bestows His blessings on mankind. A believer is cognisant of his weakness before Allah, and therefore never displays an unjust arrogance. No matter how beautiful, how rich, how intelligent or how esteemed he may be, he does not boast of these things, because he knows that it is Allah Who grants them to him. For that reason his behaviour towards other believers is also modest. He does not try to emphasise his own abilities or good features; he expects the recompense for all he does only from Allah. Contrary to the arrogance of unbelievers, believers behave with a humility, which is also reflected in their appearance. The modesty of their manner is described in the following verse:

 

The servants of the All-Merciful are those who walk lightly on the earth [i.e., with dignity but without arrogance] and, who, when the ignorant speak to them, say, “Peace”. (Surat al-Furqan, 63)

As a result of this attitude, Allah gives believers the glad tidings of Paradise:

… Your God is One God so submit to Him. Give good news to the humble-hearted. (Surat al-Hajj, 34)
