Shaykh Uthaymeen said, “The meaning of ‘Manhaj’ of the Salaf As-Saalih (the righteous redecessors) refers to following their way in aqeedah, worship and interacting with others. It is therefore a comprehensive term.
It is possible for us to rule on every specific issue that it is in compliance with the way of the Salaf or in contradiction to the way of the Salaf.
However the ‘manhaj’ of the Salaf is their way in worship, dealing with others, good manners (and aqeedah) etc..
The sign of the one who follows the ‘Manhaj of the Salaf’ is that he assumes their good manners; he lives according to their actions in the matters relating to the religion as well as worldly matters.
Whoever wants to remain safe then let him follow their righteous way.”
