"Tawassul" from the perspective of Quran, Sunnah and Scholars [Part 1]

Tawassul is one of the most important dispute points among Muslims which has caused many bloodsheds. The oppositions of Tawassul are called Wahhabi who are the followers of Muhammad ibn Abdul Wahhab. In this series, we are going to prove that the opinion of Wahhabiis on Tawassul is against Quran and Sunnah and show that unlike Wahhabism, Sunni school believes in Tawassul. So, first we introduce the views of Wahhabism on Tawassul and in the future posts, we will analyze and criticize their views.

The opinion of Muhammad ibn Abdul Wahhab on Tawassul and Ithtiqasah (kind of Supplication):

The book of Al-Durar Al-Sunnia fe Al-Jawba Al-Najdia , vol. 1, the book of Al-Aqaed , page 144:

"What we deny and oppose and because of which consider Muslims as infidels, is that if a person calls one of the prophets (e.g. Moses, Jesus pbut) or calls one of the angels (e.g. Gabriel, Michael) or performs a scarification or makes a Nadhr (Vow) or Itikaf besides the grave of prophet Muhammad (pbuh) and prays in that place and ask the prophet his/her needs, etc. This is the paganism that Quraish used to do before Islam and this is why the prophet fought Quraish."

Ref: Al-'asemi Al-Najdi Al-Qahtani, Abdul Rahman ibn Muhammad ibn Qasim, Al-Durar Al-Sunnia fe Al-Jawba Al-Najdia , vol. 1, the book of Al-Aqaed, page 144

So in the opinion of Wahhabiis, if somebody performs Tawassul or Ithtiqasah to one of the prophets or angels, he/she is an infidel and has to be killed.
