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. We ask Allaah to exalt his mention as well as that of his family and all his companions.
Whoever wants to perform a permissible matter, it is a Sunnah for him before acting to perform Istikhaarah prayer sincerely and honestly and submit the matter to Allaah. Whoever does so, then it is only good that will happen to him, whether he actually did what he wanted to do, or he did not. There are no signs or symptoms that appear on the person who performed Istikhaarah to suggest that there is good in the matter he wishes to undertake. Rather, a person should perform Istikhaarah and put his trust in Allaah.
Anyway, the Quran is the best thing a person would seek cure from, either for physical or spiritual diseases, but this happens only to the people who truly believe in it while acting according to its obligations and refrains from what it prohibits. Allaah Says (what means): {Say, 'It is, for those who believe, a guidance and cure."}[Quran 41:44]. Allaah further Says (what means): {And We send down of the Quran, that which is healing and mercy for the believers.}[Quran 17:82]. Whoever seeks cure in the Quran, he first has to believe in it and act according to it and according to the Sunnah of the Prophet .
Allaah Knows best.
