Narrated 'Azrah bin Thabit:
حَدَّثَنَا بِذَلِكَ مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ حَدَّثَنَا عَزْرَةُ بْنُ ثَابِتٍ الأَنْصَارِيُّ عَنْ ثُمَامَةَ عَنْ أَنَسِ بْنِ مَالِكٍ أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَتَنَفَّسُ فِي الإِنَاءِ ثَلاَثًا . قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
From Thumamah, from Anas that: "The Prophet (ﷺ) would breathe three times in the vessel." Another chain from Anas bin Malik: "The Prophet (ﷺ) would breathe three times in the vessel." He said: This Hadith is Hasan Sahih.
