"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.'" (Using translation from Nasāʾī 4079)
قَالَ رَسُولُ اللهِ ﷺ «مَنْ عَقَدَ عُقْدَةً ثُمَّ نَفَثَ فِيهَا فَقَدْ سَحَرَ وَمَنْ سَحَرَ فَقَدْ أَشْرَكَ وَمَنْ تَعَلَّقَ شَيْئًا وُكِلَ إِلَيْهِ»
