Shaykh Bin Baz said, “What has become common in this age, is that many of those who ascribe themselves to knowledge and calling to good (calling to Salafiyyah), fall into belittling many of their brothers who are well-known du’aat (callers to Allah, who Are upon the sunnah), and speaking against the honor of the students of knowledge and the du’aat (who call to the sunnah (Salafiyyah)).
This is done sometimes secretly in their circles, sometimes on cassettes which are then circulated amongst the people, or sometimes publicly mentioned in their gatherings in the mosques (or sometimes on social media on the internet, on blogs/websites or on YouTube and what is similar to it). And this matter opposes the command of Allaah and His Messenger (salAlllahu `alayhi wa sallam) from a number of angles…
So I sincerely advise those brothers who have fallen into slandering and maligning the du’aat (callers to Allah), that they should repent to Allaah, the Most High, for what they have written with their own hands, and what they have said with their own tongues; which may have been a cause for corrupting the hearts of some of the youths; filling their hearts with hatred and malice, and pre-occupying them away from acquiring beneficial knowledge and calling to Allaah, because of being pre-occupied with qeel and qaal (gossiping and rumor mongering); and with speech about this person and that person; and with hunting for the mistakes of people, and burdening them with this.
Likewise, I sincerely advise them that they should redress whatever they have done, and declare themselves free from the likes of these actions, through writing: or methods other than this.
They should remove whatever may have entered the minds and thoughts of those who listened to them, and they should take to doing those fruitful actions that will draw them closer to Allaah, and which will be of benefit to the worshipers.
They should beware of being hasty in pronouncing takfeer (disbelief upon another Muslim), tafseeq (calling another Muslim a faseeq (open sinner)) or tabdee (declaring other Muslims innovators) upon people, without the truth being explained, and without the proofs being established.
The Prophet (salAlllahu `alayhi wa sallam) said, “Whosoever says to his brother: O unbeliever then it will return to one of them.” The authenticity of this hadeeth has been agreed upon.”
