Sunan Ibn Majah, Hadith 3288 ⓘ
It was narrated that Ibn ‘Abbas said: “The Messenger of Allah never blew onto his food or drink, and he did not breathe into the vessel.”
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا عَبْدُ الرَّحِيمِ بْنُ عَبْدِ الرَّحْمَنِ الْمُحَارِبِيُّ، حَدَّثَنَا شَرِيكٌ، عَنْ عَبْدِ الْكَرِيمِ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ لَمْ يَكُنْ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَنْفُخُ فِي طَعَامٍ وَلاَ شَرَابٍ وَلاَ يَتَنَفَّسُ فِي الإِنَاءِ " .
