وَعَنِ ابْنِ مَسْعُودٍ كَانَ يَقُولُ: مِنَ السُّنَّةِ إِخْفَاءُ التَّشَهُّدِ. رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ

Ibn Mas'ud used to say, “It pertains to the sunna to repeat the tashahhud quietly.” Abu Dawud and Tirmidhi transmitted it, and Tirmidhi said this is a hasan gharib tradition.
