“Even if they were to grant us all the revelations and states of the heart, but did not adorn our hearts with the belief of Ahl as-Sunnah, I would consider myself destroyed and my state ruined. If they were to heap all ruins and calamities upon me, but honored my heart with the belief of Ahl as-Sunnah wal-Jama'ah, I would not be saddened at all.” (Ubaydullah Ahrar)
