Hadith 5184
Chapter 139: How many times should one say salam when seeking permission to enter - كتاب الأدب
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ رَبِيعَةَ بْنِ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ غَيْرِ، وَاحِدٍ، مِنْ عُلَمَائِهِمْ فِي هَذَا فَقَالَ عُمَرُ لأَبِي مُوسَى أَمَا إِنِّي لَمْ أَتَّهِمْكَ وَلَكِنْ خَشِيتُ أَنْ يَتَقَوَّلَ النَّاسُ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم .
The tradition mentioned above has also been transmitted by Abu Musa through a different chain of narrators in a similar manner. This version has :
‘Umar said to Abd Musa: I do not blame you, but I am afraid that the people may talk carelessly about the Messenger of Allah (May peace be upon him).
