Yahya related to me from Malik from Ayyub ibn Habib, the mawla of Sad ibn Abi Waqqas that Abu'l-Muthanna al-Juhani said, "I was with Marwan ibn al-Hakam and Abu Said al-Khudri came to him. Marwan ibn al- Hakam said to him, 'Have you heard that the Messenger of Allah ﷺ forbade blowing into drinks?' Abu Said said to him, 'Yes.' A man said to him, 'Messenger of Allah, I am not quenched from one breath.' The Messenger of Allah ﷺ said to him, 'Remove the cup from your mouth and then breathe.' He said, 'Sometimes I see something floating in it?' He said, 'Then pour it out.'"

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَيُّوبَ بْنِ حَبِيبٍ، مَوْلَى سَعْدِ بْنِ أَبِي وَقَّاصٍ عَنْ أَبِي الْمُثَنَّى الْجُهَنِيِّ، أَنَّهُ قَالَ كُنْتُ عِنْدَ مَرْوَانَ بْنِ الْحَكَمِ فَدَخَلَ عَلَيْهِ أَبُو سَعِيدٍ الْخُدْرِيُّ فَقَالَ لَهُ مَرْوَانُ بْنُ الْحَكَمِ أَسَمِعْتَ مِنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ نَهَى عَنِ النَّفْخِ فِي الشَّرَابِ فَقَالَ لَهُ أَبُو سَعِيدٍ نَعَمْ فَقَالَ لَهُ رَجُلٌ يَا رَسُولَ اللَّهِ إِنِّي لاَ أَرْوَى مِنْ نَفَسٍ وَاحِدٍ . فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ " فَأَبِنِ الْقَدَحَ عَنْ فِيكَ ثُمَّ تَنَفَّسْ " . قَالَ فَإِنِّي أَرَى الْقَذَاةَ فِيهِ . قَالَ " فَأَهْرِقْهَا " .
