Difference Between Sihr, Miracles and Charisma 

According to Al-Mazari, the difference between Sihr, Miracle and Charisma is that sihr is achieved through much efforts, by talking and doing things. Charisma does not require such an effort, and a miracle surpasses charisma in terms of challenge. Tafsir Ibn Kathir : 1/145 

According Al-Hafiz Ibn Hajar, there is a consensus that sihr only comes from a disrespectful person, and that a charisma does not appear on a disrespectful person. Al-Hafiz Ibn Hajar also stated that one should be aware of the character of the person associated with the extraordinary. If, for instance, the person in question adheres to the principle of Shari’a and shuns the serious sins, then the extraordinary acts he performs are classed as charisma; otherwise it is an act of sihr because it comes from one of its categories such as the assistance of demons. Quoted from Rawa i 'u Al-Bayan : 1/85

Warning

People are sometimes puzzled by the fact that although a person may not be a magician, although he may be a serious sinner, an innovator or a tomb-worshipper; and yet extraordinary things can still happen to him. The truth is that the extraordinary things that happen to him are the result of the assistance of demons, who beautify to people this person's bid's so that people follow it and discard the Sunnah.
