I don’t know much about Wahabism or Sufism for that matter but I have an avertion to the following:
Expecting mojizat from dead people.
Assigning superhuman powers to humans.
Believing that a human is made of noor. Believing that a human is alive for thousands of years and will return in the same flesh and blood.
Also, interpreting every Qur’anic ayah literally.
Giving credence to thousands of Ahadith, which are against common sense. Believing that the door of Ijtehad is closed. Giving so much importance to rituals that Muslims are left with no time to pursue other intellectual activities to compete with other nations.
To mention just a few.
