Assalamu'alaikom,

For those suffering from complex sihir where you have several talented magicians on the payroll of several paymasters, you can try do the following Amal to gain information on what type of sihir are actually being used against you or your loved ones:

The simplest basic version:

Istighfar 3x
Fatiha 1x
Salawat 11x
Al-Baqarah verse 177 - 11x
(a) Sura Jin verse 1-17 followed by (b) Sura Yassin verse 20 and 40 - - (repeat this for 11x) - this mean recite a-b,a-b, a-b etc for 11 times
Surah Kausar 10x
Salawat 1x
Aa-meen

Recite the above before sleeping, and insha Allah you will be given guidance dreams

wassalam
