Imaam Muqbil Bin Haadee (rahimahullaah) said:

Indeed Nad’dhaam, Abu Hudhayl and other than them amongst the enemies of the Sunnah have passed and the Sunnah of the Messenger (sallal-laahu alayhi-wasallam) has remained white and pure, and their mockery of it has not harmed it (i.e. the Sunnah).  And the contemporary enemies of the Sunnah will die and the Sunnah of the Messenger (sallal-laahu-alayhi- wa-alaa aalihee wasallam,) will remain; because Allaah has guaranteed its preservation. So He (The Most High) said:إِنَّا نَحْنُ نَزَّلْنَا الذِّكْرَ وَإِنَّا لَهُ لَحَافِظُونَ— Verily We: It is We Who have sent down the Dhikr (i.e. the Qur’an) and surely, We will guard it (from corruption)’’ [15:9]
