Believing that a certain person will be able to give shifa

Q: I would like to know if it allowed to go for Shifaa in Cape Town from a sheikh that is living in Mauritius? My sister belongs to a Jaama that makes thikr and gives food. This sheikh gives shifaa and they wear a green cloth over them while thikr is being performed.She puts pictures of this sheikh on her blackberry and he have very long hair.The sheikh said that angels are in your hair if it is long so she grew her hair and says that should she have a son she will grow his hair long also.

They have been "called" to Mauritius to visit the sheikh and they go but they do not want to go to Makkah and perform their Hajj now. They receive colors of clothes for the higher there spirituality goes. They say everyone should join and ask for anything and the sheikh will ask Allah. We as muslims can ask Allah directly so should we need to go through a sheikh in Mauritius? I believe that thikr is part of the quraan and you are making Allah higher but is this all allowed in Islam to almost like worship this sheikh?

ثلاثون كذابون قبل يوم القيامة

س: كثر في زماننا أشد الإكثار - الناس الذين يقرون عن أنفسهم أنهم من الأنبياء، و يخرج من بعضهم الإستدراجات (و أكثرهم يرغبون بذلك المصالح الإقتصادية). أنا شخصيا رأيت في التلفاز الرجل الذي قال عن نفسه - أنه الرسول عيسى (ظهوره الثاني)؛ والناس الذين يقولون عن أنفسهم - أنهم الظهور الثاني للنبي عيسى - في زماننا كثير جدا (خاصة في الديار النصرانية). أظن أن ذلك من علامات تقريب يوم القيامة. هل هناك أحاديث ثابتة تخبر عن ذلك (يعني عن إكثار الناس الذين يقولون عن أنفسهم انهم من الأنبياء - قبل يوم القيامة)؟
