Chosen Islamic Manners

'Where is the one who asked about the Final Hour?' He then answered him. (Bukhari)

*One should speak slowly, deliberately and succinctly. It is narrated that a person could repeat everything the Messenger of Allah () said. The Prophet () would speak deliberately and slowly so that people could memorize what he was saying.
*One should speak in a low voice and not raise his voice excessively. Allah says:

And lower your voice. Verily, the harshest of all voices is the voice (i.e. braying) of a donkey. (31:19)

*One should avoid using words or phrases which are unlawful in Shari'ah³⁸; such as, swearing by other than Allah, saying: 'all people are doomed'³⁹ and so on.
*One should not talk boastfully about himself. Allah says:

So do not claim yourselves to be pure. (53:32)

One should avoid using the royal plural when referring to himself, i.e. one should not say: 'We have finished this and that.'
*One should be careful when talking and not hurt the feelings of others. Imam Ibn al-Qayyim, may Allah have mercy on him, said: 'Among people are those who are similar to a sickness. They are hated, one cannot benefit from their words. They do not listen, nor do they know their status (so that they may respect themselves).'
