When the Messenger of Allah ﷺ sneezed, he placed his hand or a garment on his mouth, and lessened the noise. The transmitter Yahya is doubtful about the exact words khafada or ghadda (lessened).  

أبو داود:٥٠٢٩حَدَّثَنَا مُسَدَّدٌ حَدَّثَنَا يَحْيَى عَنِ ابْنِ عَجْلاَنَ عَنْ سُمَىٍّ عَنْ أَبِي صَالِحٍ عَنْ أَبِي هُرَيْرَةَ قَالَ

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا عَطَسَ وَضَعَ يَدَهُ أَوْ ثَوْبَهُ عَلَى فِيهِ وَخَفَضَ أَوْ غَضَّ بِهَا صَوْتَهُ شَكَّ يَحْيَى

كَانَ رَسُولُ اللهِ ﷺ إِذَا عَطَسَ وَضَعَ يَدَهُ أَوْ ثَوْبَهُ عَلَى جَبْهَتِهِ وَخَفَضَ أَوْ غَضَّ مِنْ صَوْتِهِ
