Our beloved Master, the Master of all Sufis, the Prophet (sall-Allahu 'alaihi wa sallam) had explained that Muslims would part into seventy-three groups in respect to imaan, and that only one of them would be right and the others wrong. And happen it did. The group that was given the good news of being on the right way is called the Ahl as-Sunnat wal-Jamaat.
The remaining seventy-two groups, which were declared to be wrong, are called the groups of bidat, that is, heretics. None of them are disbelievers. All of them are Muslims. But, if a Muslim who says he belongs to any of the seventy-two groups disbelieves any information that has been declared clearly in Quran, in Hadith ash-Sharif or that has spread among Muslims, he becomes a disbeliever.
There are many people today who, while carrying Muslim names, have already dissented from the Madhhab of the Ahl as-Sunnat and have become heretics or non-Muslims."
The Wahhabis, while claiming to love all as-Sahabat al-kiram, follow not their path but their own heretical path which they ascribe to as-Sahaba. They do not like the scholars of Ahl as-Sunnat, great Sufis and Ahl al-Bait and slander all of them. They suppose that they alone are Muslims.
The 'ulama of Ahl as-Sunnat collected 'ilm at-tasawwuf by learning this second task of our Prophet ('alaihi 's-salam) from the Twelve Imams (rahmat-Allahi ta'ala 'alaihim). Some people do not believe in awliya', karamat or tasawwuf. This shows that they have no connection with the Twelve Imams. If they had followed the Ahl al-Bait, they would have learned this second task of our Prophet from the twelve Imams and there would have been many scholars of tasawwuf and awliya' among them. But there have not been any, and besides, they do not even believe that such scholars could exist. It is obvious that the Twelve Imams are the Ahl as-Sunnat's imams. It is the Ahl as-Sunnat who love the Ahl al-Bait and follow the Twelve Imams. To become a scholar of Islam, one has to be an heir of Rasulullah ('alaihi 's-salam) in these two tasks. That is, one has to be an expert in these two branches of knowledge. 'Abd al-Ghani an-Nabulusi (rahmat-Allahi ta'ala 'alaih), one of such scholars, quoted, on pages 233 and 649 in his work Al-Hadiqat an-nadiyya, the hadiths describing the spiritual rules of Qur'an al-karim and pointed out that disbelieving these rules indicates ignorance and misfortune.
May Almighty Allah honor us all with the prosperity of following Prophet Mustafa (sall-Allahu 'alaihi wa sallam), who is the spiritual Master of this and the next world and who is the highest of all the people in every respect. Because Almighty Allah likes those who obey and follow him, a tiny act of following him is more exalted than all the worldly advantages and all the blessings of the next world. Real superiority consists of adapting oneself to his sunnat, and the honor and virtue of humanity entails following his Shariat.
