Then the author mentioned the hadith of 'Aishah (may Allah be pleased with her): that the Prophet (peace and blessings be upon him and his family) used to speak in a clear, distinct manner.

The Shaykh : Then the author mentioned the hadith of 'Aishah (may Allah be pleased with her): : meaning distinct, where the letters do not overlap one another, nor the words overlap one another, such that if a counter wished to count them, he could count them due to the extreme deliberation of the Prophet (peace and blessings be upon him and his family) in his speech. Likewise, a person should not let his speech overlap in a way that is unclear to the listener, because the purpose of speech is to make the addressee understand, and the closer it is to clarity, the more preferable and better it is.
Furthermore, a person should, when adopting this method—meaning, when making his speech clear, distinct, and repeating it three times for one who does not understand—be aware that he is following the Messenger of Allah (peace and blessings be upon him and his family), so that he may thereby attain reward and the understanding of his Muslim brother. Likewise, with all the Sunnahs, keep in mind that you are following your Prophet (peace and blessings be upon him and his family), so that your following is realized. And success is from Allah.
