حَدَّثَنَا خَلاَّدُ بْنُ يَحْيَى، قَالَ: حَدَّثَنَا مِسْعَرٌ، عَنْ ثَابِتِ بْنِ عُبَيْدٍ قَالَ: أَتَيْتُ مَجْلِسًا فِيهِ عَبْدُ اللهِ بْنُ عُمَرَ، فَقَالَ: إِذَا سَلَّمْتَ فَأَسْمِعْ، فَإِنَّهَا تَحِيَّةٌ مِنْ عِنْدِ اللهِ مُبَارَكَةً طَيْبَةً.
Thabit bin Ubaid (may Allah have mercy on him) says: I came to a gathering in which Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) was also present. He said: When you greet with Salam, let others hear it, that is, greet with a loud voice, because this is a blessed and pure gift from Allah Almighty.
