What is the ruling about the group called "Ahl al-Sunnah Wa al-Jamaah" who are known by the name of "Wahabi"?

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

al-Shawkani (may Allah's Mercy be upon him) said in his book 'al-Badr al-Tali': 'In 1125 A.H. Our Imam (of Yemen) received two good books from Muhammad Ibn 'Abdul Wahhab . One of the two books contains research works of Muhammad Ibn Abdul Wahhab about guiding people to monotheism and leading them away from polytheism done by those who believe in help of tomb dwellers. For sure, they are good works that are based on the Qur'an and Sunnah' .
al-Sheikh Muhammad Bashir al-Sahwani , an Indian scholar of Hadith in his book 'Sianat ul-Insan (Maintenance of a human being) said: 'It is not known that al-Sheikh (i.e. Muhammad Ibn 'Abdul Wahhab (may Allah's Mercy be upon him) had some special opinion that is not agreed upon among Muslims nor among Ahl-al-Sunnah wal-Jama'a. No doubt that all his opinions concerning monotheism of Names and Attributes of Allah as well as worshipping Him are agreed upon among Muslims with the exception of followers of al-Mu'tazila, al-Jahmiyyah and worshippers of tombs. Opinions of Ibn 'Abdull Wahhab constitute part and parcel of what Prophets and Messengers and Revealed Books agreed upon' .
al-Jibirti , an Egyptian historian, praised al-Sheikh and his sons and followers in the book of 'Ajaeb al-Athar'.
Many just scholars as No'man Khir al-Deen al-Amawi , Mahmood Shukri al-Aloosi , the prince Shakeeb Arsalaan and others praised al-Sheikh Muhammad Ibn 'Abdul Wahhab and his sons since they read their good books.
Allah knows best.
