Daily Hadith Sat 19-Jan-2019 - 12 Jumada al-Ula 1440 حديث اليوم
Clarity of Discourse
Anas (May Allah be pleased with him) reported: Whenever the Prophet (PBUH) said something, he would repeat his words thrice so that the meanings would be understood fully; and whenever he came upon a group of people, he would greet them, and he would repeat salutation thrice.[Al-Bukhari and Muslim].


Commentary:
To lay stress on a point thrice or to repeat greetings, according to this Hadith, is preferable. It is particularly so when a situation so demands and when explaining a point to the audience once and twice may not be enough.

عن أنس رضي اللَّه عنه أن النبي صَلّى اللهُ عَلَيْهِ وسَلَّم كانَ إذا تَكَلّم بِكلِمَةٍ أعَادها ثَلاثاً حَتَّى تُفْهَم عَنهُ ، وإذا أتَى عَلى قَوْمٍ فَسَلَّمَ عَلَيْهِمْ سَلَّمَ علَيْهِمْ ثَلاثاً . رواه البخاري .
