Kitāb al-Ghayba > Refutation of all sects, which believed in Imamate of someone other than Master of the Age (a.s)
Hadith #6

واحتجاجهم بما روي من أن صاحب هذا الأمر يحيا بعد ما يموت وأنه سمي قائما لأنه يقوم بعد ما يموت، باطل لأن ذلك يحتمل لو صح الخبر أن يكون أراد بعد أن مات ذكره حتى لا يذكره إلا من يعتقد إمامته فيظهره الله لجميع الخلق،على أنا قد بينا أن كل إمام يقوم بعد الإمام الأول يسمى قائما.

The argument, which is based on the tradition that “the Master of this Affair will live after he dies” and that he has been named Qaim, since he will rise after he dies, is invalid, because first the tradition is not reliable, and even if it is reliable, it can be interpreted to mean that he will rise after his name dies, that is, no one mentions him, except those who believe in his Imamate and then Allah will manifest him to all. Besides, we have established that every Imam, who stands in place of a previous Imam, is called the Qaim.
