If you speak to a guest or any other person, whether in a gathering or alone, make sure that your voice is pleasant, with a low audible tone. You may raise your voice in accordance to the need. Raising your voice unneccessarily is contrary to proper manners and indicates lack of respect for the person to whom you are talking. This manner should be maintained with friends, peers, acquaintances, strangers, the young and the old. It is more important to adhere to this with one’s parents or someone of their status or those elderly and notable persom whom you ought to respect.
The Qur’án tells us that the advice of Luqmán, The Wise, to his son was:
وَٱغۡضُضۡ مِن صَوۡتِكَۚ
“And lower your voice,” [Surah Luqman:19]
He directed him to speak in a gentle manner , for speaking loudly is detested and ugly.
Verse two and three of Surah Hujurat read:
“O ye who believe! raise not your voices above the voice of the Prophet, nor speak aloud to Him In talk, As ye may speak aloud to one another, Lest your deeds become vain and ye perceive not. Those that lower their voices In the presence of Allah’s Messenger,- their hearts has Allah tested for piety: for them is forgiveness and a great reward.”
Sayyiduná ‘Abdullah Ibn Zubair [Radallahu anhuma] said that: “After the revelation of these verses, whenever Sayyiduná ‘Umar Ibn Al-Khattab [Radiallahu anhu] wanted to address Rasulullah [Sallallahu álayhi wa sallam], he (‘Umar [Radallahu anhu]) would talk as if he was whispering. Rasulullah [Sallallahu álayhi wa sallam] would even enquire about some of what Sayyiduná ‘Umar [Radiallahu anhu] said, because he did not hear him well.” [Sahih Bukhari]
Hafidh Adh-Dhahabi [Rahimahullah] wrote in his biography of Imam Muhammad Ibn Sírín [Rahimahullah], the eminent scholar and great Tábi’í, that:
“Whenever he was in his mother’s presence, he would talk in such a low tone that you would think that he was ill.” [Tárikhul Islam, vol. 4 pg. 197.]
In his biography of ‘Abdullah Ibn Awn Al-Basri [Rahimahullah], a student of Imam Ibn Sírín [Rahimahullah] and one of the famous scholars, Hafidh Adh-Dhahabi [Rahimahullah] noted:
“Once, his mother called him and because he responded with a voice louder than hers, he was fearful and he repented by freeing two slaves.”
‘Ásim Ibn Bahdalah Al-Kufi [Rahimahullah], the famous qári said, “I visited Sayyiduná ‘Umar ibn ‘Abdul ‘Aziz [Rahimahullah] and a man spoke loudly. To this Sayyiduná ‘Umar [Rahimahullah] replied: “Stop! You need not talk loudly. You should only talk loud enough to make your listeners hear.” [Tárikh Dimashq]
