Hadith 4079
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا أَبُو دَاوُدَ، قَالَ حَدَّثَنَا عَبَّادُ بْنُ مَيْسَرَةَ الْمِنْقَرِيُّ، عَنِ الْحَسَنِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ عَقَدَ عُقْدَةً ثُمَّ نَفَثَ فِيهَا فَقَدْ سَحَرَ وَمَنْ سَحَرَ فَقَدْ أَشْرَكَ وَمَنْ تَعَلَّقَ شَيْئًا وُكِّلَ إِلَيْهِ " .
It was narrated that Abu Hurairah said:
"The Messenger of Allah [SAW] said: 'Whoever ties a know and blows on it, he has practiced magic; and whoever practices magic, he has committed Shirk; and whoever hangs up something (as an amulet) will be entrusted to it.'"
