عَنْ عِكْرَمَةَ عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا إِنْ شَاءَ اللَّهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَهَى عَنْ أَنْ يُتَنَفَّسَ فِي الْإِنَاءِ أَوْ يُنْفَخَ فِيهِ
Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) forbade breathing into a vessel and blowing into it.
