Hadith 31-262

وَبِإِسْنادِهِ عَنْ عَلِيِ‏ عَلَيْهِ السَّلامُ قالَ: أَنَا عَبْدُ اللَّه، وَأَخُو رَسُولِهِ، لا يَقُولَها بَعْدي إِلاّ كَذَّابٌ.

According to the same documentation, on the authority of Ali (a.s.), “I am God’s servant and the brother of His Messenger (a.s.). Whoever claims anything else is a liar.”
