How can I cure black magic?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad  is His slave and Messenger.

First of all, you have to know that magicians are not an authentic source for the truth, so you should not trust them and hold enmity to your in-laws or any other people because of what magicians say. As for the cure from magic, it should be done through the legal Ruqyah from the Quran and the authentic Sunnah. In fact, the Quran is a remedy for all diseases if the person believes that Allaah cures by it. We suggest that you read the Quran as much as possible. You should read Chapter Al-Baqarah (Quran 2) and Chapters 112, 113 and 114 as often as possible.

We also suggest that you take some water, enough to bathe in, and you read the following verses on it:

1 – Al-Kursy [Quran 2: 255]

2 – Al-Kaafiroon [Quran 109]

3 – Al-Ikhlaas [Quran 112]

4 – Al-Falaq [Quran 113]

5 – An- Naas [Quran 114]

6 - Read the verses about magic:

a) Allaah Says (what means): {And We inspired to Moses, “Throw your staff,” and at once it devoured what they were falsifying. So the truth was established, and abolished was what they were doing. And they [i.e. Pharaoh and his people] were overcome right there and became debased.} [Quran 7:117-119]

b) Allaah Says (what means): {Moses said, “Do you say [thus] about the truth when it has come to you? Is this magic? But magicians will not succeed." They said, {Have you come to us to turn us away from that upon which we found our fathers and so that you two may have grandeur in the land? And we are not believers in you.” And Pharaoh said, “Bring to me every learned magician.” So when the magicians came, Moses said to them, “Throw down whatever you will throw.” And when they had thrown, Moses said, “What you have brought is [only] magic. Indeed, Allaah will expose its worthlessness. Indeed, Allaah does not amend the work of corrupters. And Allaah will establish the truth by His words, even if the criminals dislike it.”} [Quran 10:79-82]

c) Allaah Says (what means): {They said, “O Moses, either you throw or we will be the first to throw.’ He said, “Rather, you throw.’ And suddenly their ropes and staffs seemed to him from their magic that they were moving [like snakes]. And he sensed within himself apprehension, did Moses. We [i.e. Allaah] said, “Fear not. Indeed, it is you who are superior. And throw what is in your right hand; it will swallow up what they have crafted. What they have crafted is but the trick of a magician, and the magician will not succeed wherever he is.”} [Quran 20: 65-69]

Then you should drink from this water and wash yourself with it and let your husband do the same thing. This is a remedy for magic, Allaah willing.

We also urge you to regularly repeat the morning and evening known Thikr (legislated mention of Allaah) as well as the Thikr when leaving and entering the home, when going to bed, waking up …. etc.

Moreover, you should perform the prayer at its prescribed fixed time. You should also repent to Allaah from going to any magician as magicians are disbelievers.

We ask Allaah The Almighty to cure you and your husband and protect you both from all evil and harmful matters.

Finally, we do not have the address of any person who could do legal Ruqyah for you in Riyadh, but we suggest you to contact the Permanent Council of Fatwa in Saudi Arabia and they may help you find someone who could perform legal Ruqyah for you in order to relieve you from what you mentioned.
