问18：“除真主外别无应受崇拜的主”这句作证的话是什么意思？
Q 18: What does the testimony, "There is no god but Allah" mean?
A ---意思是：除了真主，没有任何人有权被崇拜，真主在崇拜和主权上没有伙伴，也没有对手。至高的真主说：
A ---It means that none has the right to be worshipped but Allah Who has no partners or rivals with Him in Worship or Dominion. Allah the Most High says:
这是因为真主——祂是真理（唯一真实的主，在万有之中，祂没有伙伴，也没有匹敌），而他们（多神主义者）舍真主而祈求的，那都是虚妄（Balil）。真主确实是至高的，至大的。（朝觐章，62）
That is because Allah -He is the Truth (the only True God of all that exists, Who has no partners or rivals with Him), and what they (the polytheists) invoke besides Him, it is Balil (falsehood). And verily, Allah - He is the Most High, the Most Great. (Al-Hajj, 62)
