What advice or prayer can you offer for a friend’s sister who has been in ICU for 3 months with various illnesses?

Mufti Sahab Assalam alekuml. 1 of my friends sister(married) is in Hospital since last 3 months in ICU. Sice 2 years she is suffring from many diseases, as soon as 1 problem solve then other comes e.g. initially she had T.B. in her head after fever in Head, then preganancy problem (in only 6 months delivery happand with dead baby), now the condition is that Dr. is telling that blood is clotted in her brain viens due to which is is not able to do any body movement. Dr. is telling ‘Ony god can help’ . She was used to offer 5 times prayer. Many Maulanas also came they fail to do anything everybody is saying that this is Ruhani problem, because everytime her parents plan to discharge her, new disease catches her. Few days back we counsult an Almil he told this is internal(Ruhani) problem and this needs a powerfull Alim to clear this. Please give us any suggestion or Duwa for this.
