4.4 The Difference Between The ‘aqīdah And The Sharī’ah Rule (hukm Shar’i)
Linguistically, ‘aqīdah (creed) means
The matter on which the heart has tied a knot (belived in firmly). The meaning of tying a knot is to be sure of, that is, believe in it decisively, this is general, which includes belief in everything. However, the belief in a certain matter is examined in terms of the thing in which the conviction has taken place. If it was a fundamental matter or one that is branching out from a fundamental matter then it is correct to call it an ‘aqīdah (creed) and it is correct for one to take it as a fundamental criterion for other beliefs, so the heart tying a knot on it will have a manifest impact. If the matter in which one has conviction is not a fundamental matter or is branching out from a fundamental matter then it will not be part of the ‘aqīdah (creed), this is because the heart tying a knot on it will not have a manifest impact. In believing in it one will not find in it any reality or any benefit. And when the heart's tying a knot on any subject matter has an effect, it will push him to determine his stance towards it in terms of belief and denial, and then it will be part of the ‘aqīdah (creed).
The ‘aqīdah (creed) is a comprehensive thought concerning the universe, man and life, what preceded this wordly life and what is to follow it, and the relationship of this life with what preceded it and what is to follow it. This is the definition of every ‘aqīdah (creed) and it applies to the Islamic ‘aqīdah (creed). Included in it are the unseen matters. So the belief in Allah , His angels, His books, His Messengers, the Last Day, divine fate and destiny (qadā’ wal qadā’r), that good and bad is from Allah is the Islamic ‘aqīdah (creed). The belief in Paradise (jannah), Hellfire (nar), angels, shaytan’s etc is from the Islamic ‘aqīdah (creed), thoughts and whatever relates to it. Also narrations and the unseen things that cannot be percieved are considered from ‘aqīdah (creed).
