Shaykh Abdul Aziz Al-Raajihi was asked:
What is the definition of the Aqeedah of the Salaf?
“The Aqeedah of the Salaf is what has come in the Book of Allah and the Sunnah of the Messenger of Allah (ﷺ) from Belief in Allah, the Angels, His Books, His Messengers, the Last Day, and in Qadr, the good of it and the bad of it. This is general and the detail of that is well-known in the texts”
