696/1 - Anas (may Allah be pleased with him) reported: “Whenever the Prophet (may Allah’s peace and blessings be upon him) made a statement, he would repeat it thrice until he is understood. Whenever he greeted a group of people, he would greet them thrice.” [Narrated by Al-Bukhāri]
1) It is recommended to speak in a clear manner that can be understood by the addressee. This is part of the speaker’s eloquence.
2) It is better to repeat the speech in case the addressee does not understand; but if he understands without repetition, then there is no need to repeat, for he said in the Hadīth: “until he is understood”.
3) Repeating thrice is the maximum that makes the speech clear.
697/2 - ‘Ā’ishah (may Allah be pleased with her) reported: “The Prophet’s speech was clearly articulated that anyone who listened to him could understand it.” [Abu Dāwūd]
