Salaam all,
I agree with you, Truth Seeker.
I believe in the healing power of prayers. Holistic doctors recommend praying be included in the treatment regimen along with medicine, diet, exercise, visualization.
I was told that Shia pick up a tiny bit of the earth of Karbala and recite Surah al Fatihah, Surah Ya Sin, Surah al Qadr, Surah Al Kafirun, Surah al Ikhlas, Surah al Falaq, Surah al Nas & Ayatal Kursi, and the following dua:
O Allah, in the name of Muhammad, Your servant, Your dearest friend. Your prophet, Your messenger, Your trustee; in the name of Amir aI Mumeneen Ali ibn Abi Talib, Your servant, brother of Your messenger; in the name of Fatimah, daughter of Your Prophet and wife of Your Wali; in the name of Hasan and Husayn, in the name of the rightly guided guides; in the name of the guardian angel; in the name of the body covered by it; in the name of all angels and messengers, make this earth cure my disease and also of those who beseech You for removal of ailments, pains, diseases; and keep me (and all the beseechers) protected from all fears. O Allah, for the sake of Muhammad and his family, let this (earth) give me useful knowledge, abundant means of livelihood, let it cure my pains and diseases, let it keep me safe from misfortunes; injuries, all kinds of pains. Verily You have power over all things. O Allah, the Lord of this sacred, blessed earth and the angel who descended on it and the vicegerent who is resting under it, send blessings on Muhammad and on the children of Muhammad, and let it help me and benefit me. Verily You have power over all things
Reciting the surahs is fine but listing the names of all others borders on shirk, I believe.
Having a positive outlook helps the diseased body so does the hope that if it is the 'taqdir' of Allah, you will get better whether you recite 10 times or 100 times .
I don't like these magical formulas recited X number of times . You pay more attention to counting than experiencing the Presence of God in the moment.
