Ruling on one who thinks that sihr is OK so long as it does not cause any problems

What do you think abouta man who used ruqyah,but he did not think
thatit helped him, so he turned from that to sihr (magic, witchcraft),
and he says, I think that it is OK so long as it does not cause any
problems?
Praise be to Allaah.
Sihr is evil and is kufr. If a sick person is not cured by reading
(Qur'aan and du'aa's), then we should note that medicine does not
guarantee a cure either, because not every treatment produces the
desired result. Allaah may delay the healing for a long time, or the
person may die from thissickness. It is not a condition of treatment
that the person should be healed. If a person is treated by reading
Qur'aan and does not recover, that is not an excuse for turning to
sihr, because we are commanded to take the permissible means
prescribed in sharee'ah, and we are forbidden touse haraam means. The
Prophet (peace and blessings of Allaah be upon him) said, "O slavesof
Allaah, seek treatmentbut do not seek treatment with that which has
been forbidden to you." And itwas narrated that he (peace and
blessings of Allaah be upon him) said: "Allaah does not make your
healing in that which He has forbidden to you."
All things are in the handof Allaah, may He be glorified. He is the
One Who heals whomsoever He wills, and He decrees sickness and death
for whomsoever He wills, as He says (interpretation of the meanings):
"And if Allaah touches you with harm, none canremove it but He, and if
He touches you with good, then He is Able to do all things" [al-An'aam
6:17]
"And if Allaah touches you with harm, there is none who can remove it
but He; and if He intends any good for you, there is none who can
repel His Favour which He causes it to reach whomsoever of His slaves
He wills. And He is the Oft-Forgiving, the Most Merciful [Yoonus
10:107]
So the Muslim must be patient and seek rewardwith Allaah. He must
limit himself to the means that Allaah has permitted, and beware of
that which Allaah has forbidden, whilst also believing that the decree
of Allaah is beneficial and that His command cannot be put back, as
Allaah says (interpretation of the meanings):
"Verily, His Command, when He intends a thing,is only that He says to
it, 'Be!' and it is! [Yaa-Seen 36:82]
"And you cannot will unless (it be) that Allaah wills the Lord of the
'Aalameen (mankind, jinn and all that exists) [al-Takweer 81:29]
And there are many similar aayaat.
