Humility is another important factor in the speech of the faithful. Attention to this matter is drawn to this aspect of their morality in the Qur'an in this verse:
"The servants of the All-Merciful are those who walk modestly on the earth and, who, when the ignorant speak to them, say, 'Peace'."
The faithful are humble through their knowledge that no matter what qualities they may possess, all are favors from Allah and that He can take them back whenever He wishes.
Allah notifies the faithful of this with the words of the following verse, "Do not strut arrogantly about the earth. You will certainly never split the earth apart nor will you ever rival the mountains in height.
Human beings are truly powerless in the light of the boundless might of Allah. Allah's knowledge encompasses everything; He is the Creator and the Possessor of every thing. For this reason, the believers act with cognizance of the degradation they will suffer when confronted by Allah on the Day of Judgment, if they become proud of something that does not truly belong to them. Even in that in which they are outstanding, they humble themselves, acknowledge their deficiencies and speak in recognition of their powerlessness. Even if those they talk to are lacking in the same own qualities, Muslims never become arrogant and boastful, because, in the following verse, Allah has informed them that He does not love vain people, Do not avert your face from people out of haughtiness and do not strut about arrogantly on the earth. Allah does not love anyone who is vain or boastful. (Surah Luqman: 18)
When speaking on a subject, Muslims do not talk in a condescending manner; that is, they talk with an awareness that the matter in question also applies to themselves. As is pointed out in the verse, "No indeed! Truly man is unbridled seeing himself as self-sufficient"
(Surat al-‘Alaq: 6-7) believers act in the knowledge that, if they admire themselves vainly, their better qualities may be in detriment and they may fall into great error. When speaking on a subject they know well, they do not become conceited and try to bring attention to themselves. On the contrary, they adopt a manner of speaking that reflects a recognition that it is only Allah Who grants the power of speech, and it is only Allah Who possesses the knowledge of all things.
In the verse "Worship Allah and do not associate anything with Him. Be good to your parents and relatives and to orphans and the very poor, and to neighbors who are related to you and neighbors who are not related to you, and to companions and travelers and your slaves. Allah does not love anyone vain or boastful." (Surat an-Nisa': 36), Allah reminds people to behave well and not to be boastful towards those they speak to. Allah has instructed us to show humility to our parents, our close friends and casual acquaintances, orphans and the needy. Behaving humbly towards those one regards well but arrogantly towards those one looks down upon, is not in accordance with the morality of the Qur'an. People are responsible for adhering to this in all instances. Muslims also know that speaking boastfully when faced with an egotistical person, offering the excuse, "Never mind, he's arrogant as well," is not correct either. The Muslim way of speaking requires speaking in the knowledge that everywhere and at all times Allah is witness to every word, and this sense of moral obligation can only be developed by following the teachings of the Qur'an.
