Respected hakeem sahib, Assalamoalaikum! I have a deed that is very useful for cancer and it is quite unanswerable. May Allah save everyone from cancer. If someone caught this dangerous disease, even if he reached the last stage, if Allah almighty has meant any health for him, then he shall certainly be cured in 40 days. The deed is as follows: Recite durood sharif Ibrahimi 11 times before the beginning and at the end. In between, recite surah Maryam once and make dum on water and give the same water for the whole day to the patient. There should not be a single break in between. By the will of Allah the cancer will be cured. (J, Sh)
