sahih

This hadith is also transmitted by Ahmad b. Sa'id, Habban, Sulaiman b. Mughira on the authority of Anas who said:

When the verse was revealed:" Do not raise your voice louder than the voice of the Messenger," no mention was made of Sa'd b, Mu'adh in it.

وَحَدَّثَنِيهِ أَحْمَدُ بْنُ سَعِيدِ بْنِ صَخْرٍ الدَّارِمِيُّ، حَدَّثَنَا حَبَّانُ، حَدَّثَنَا سُلَيْمَانُ بْنُ الْمُغِيرَةِ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، قَالَ لَمَّا نَزَلَتْ ‏{‏ لاَ تَرْفَعُوا أَصْوَاتَكُمْ فَوْقَ صَوْتِ النَّبِيِّ‏}‏ وَلَمْ يَذْكُرْ سَعْدَ بْنَ مُعَاذٍ فِي الْحَدِيثِ ‏.‏
