I totally agree with brother diwana that there is no such thing as black, red, white or a yellow magic !
Surah Baqarah verse 102: They followed what the evil ones gave out (falsely) against the power of Solomon; the blasphemers were not Solomon but the evil ones teaching men magic and such things as came down at Babylon to the Angels Harut and Marut. But neither of these taught anyone (such things) without saying: "We are only for trial so do not blaspheme." They learned from them the means to sow discord between man and wife. But they could not thus harm anyone except by Allah's permission. And they learned what harmed them not what profited them. And they knew that the buyers of (magic) would have no share in the happiness of the Hereafter. And vile was the price for which they did sell their souls if they but knew!
Surah Aaraaf verses 116-118:
116 Said Moses: "Throw ye (first)." So when they (the magicians) threw, they bewitched the eyes of the people and struck terror into them: for they showed a great (feat of) magic.
117 We put it into Moses's mind by inspiration: "throw (now) thy rod": and behold! It swallows up straightway all the falsehoods which they fake!
118 Thus Truth was confirmed and all that they did was made of no effect.
Thus to answer the question if ‘magic exists’, in light of the Quraan it is 'Yes'!
But if all the Jinns and all the magicians of the world were to get together and plot or plan to bring about any harm upon anyone, they would not even be able to damage even one hair on the body of that individual without the precise Will and Permission of Allah (swt). We need not fear jinns or magicians or their magic or any other evil thing since all Power n Strength belongs to Allah(swt) alone and one can neither harm nor benifit without His will and Permission.
Surah Fatir verse 2: What Allah out of His Mercy doth bestow on mankind there is none can withhold: what He doth withhold there is none can grant apart from Him: and He is the Exalted in Power Full of Wisdom.
Al-Tirmidhi Hadith 1019:
Narrated by Abu Sa'id al-Khudri "The Prophet (saws) used to seek protection against the Jinn and the evil eye till Surahs al-Falaq and an-Naas were revealed. After they were revealed, he (saws) stuck to them and discarded everything beside them".
Al-Tirmidhi Hadith 4563:
Narrated by Abu Sa'id al-Khudri: "Allah's Messenger (saws) used to seek refuge in Allah from jinn and the evil eye in men till the Mu'awwidhatan (Surah 113 Al-Falaq and Surah 114 An-Naas) were revealed, after which he (saws) made use of them and abandoned everything else".
Thus practice of the Prophet Mohammed (pbuh) was to recite the Surah Al-Ikhlas, Surah Al-Falaq, and Surah An-Naas at least three times in the mornings and the evenings, and also when he (saws) retired for the night to sleep...( FORTRESS FOR MUSLIMS)
Thus, Allah(swt) has given us solution for magic or evil eye, so let us not leave the boundaries of Islam and earn His wrath by doing wrong things.
Allah knows best.
