This is it. If those people (the hasty brothers declaring everyone as mubtadi) have really sat down to read about the Salaf, they would not get themselves into the quagmire they are today.
The Issue that arose between Imaam Ahmad and Yahya bn Maeen, Ibn Madeenee and others is another example, after they were strong friends. Why did the Ummah reject Imaam Ahmad's verdict on them.
Abu Daawud did not have reports from Bukhari in his Sunan but had from teachers of Bukhaaree such as Musaddad, Ibn Rahuway, Ibn Madeenee, Ibn Qutaybah, etc.
Imaam Muslim too did not have reports from Bukhaaree, in His Saheeh, there are reasons for this.
Abu Zur'ah and Abu Haatim had to abandon Bukhaaree on the advice of Imaam Muhammad bn Yahya Azzuhlee. We all know who was eventually wrong here.
Or why did the scholars of hadeeth reject Abu Daawud's verdict on his son, Abubakr, the author of the popular Haaiyah, that he is a liar.
People claiming to be salafis really need to read about our Salaf very well lest they fall into great errors in future.
People need to really farabale gan an ni o.
Please let's learn first.
To understand today's scholars you have to understand yesterday's scholars from the pious generations.
