Proving the Possibility of another Emersion in the Certain Signs of Appearance

Bada' (lit. Emersion/chang) is one of the very important and influential teachings in the Imamiyyah thought. This teaching is of a very vast domain and is brought up in the issue of the certain signs of twelfth Imam (AS) appearance. This issue's origin is the narrations denoting the possibility of another emersion in the certain destinies including the certain sings of Imam's appearance. There is also a special narration from Imam al-Jawad (AS) for the possibility of Bada' in the certain signs. On the contrary, there are narrations denoting the impossibility of change in the certain destinies. Because of the strength of text and document as well as agreement with reason, the narrations denoting the possibility of change in the certain destinies are preferable, because believe in impossibility of change in the certain affairs results in God's inability in changing the destinies. In addition, possibility of Bada' in certain affairs has Quranic evidence.
