حَدَّثَنَا عَبْدَةُ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا عَبْدُ الصَّمَدِ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا ثُمَامَةُ بْنُ عَبْدِ اللَّهِ، عَنْ أَنَسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ كَانَإِذَا تَكَلَّمَ بِكَلِمَةٍ أَعَادَهَا ثَلاَثًا حَتَّى تُفْهَمَ عَنْهُ، وَإِذَا أَتَى عَلَى قَوْمٍ فَسَلَّمَ عَلَيْهِمْ سَلَّمَ عَلَيْهِمْ ثَلاَثًا‏.‏
Translation
Narrated Anas

Whenever the Prophet (ﷺ) spoke a sentence (said a thing), he used to repeat it thrice so that the people could understand it properly from him and whenever he asked permission to enter, (he knocked the door) thrice with greeting.
