Because forecasting their appearance incites Allah's wrath...
'Those who fix the time are liars, those who hasten are destroyed and those who submit are safe.'[^6] Then those who make claims about reappearance being very near, to attract the people towards Imam-e-Zamana (a.t.f.s.) and provide some background for reappearance in the name of ظهور صغرا (minor reappearance), are themselves deviated and misguide others.
The duty of the awaiter is to submit to Allah's destiny with regards to the time of reappearance and never despair of Imam's (a.t.f.s.) reappearance at morning or evening and consider it to be very near. But he must not fall prey to hastening and not to pull oneself or others towards deviation and doubt by creating a false and deceptive atmosphere of reappearance being very near. Therefore, considering reappearance as near should never lead one to forecast the time of reappearance.
The former is praised and the latter condemned and both are totally distinct from each other. Intention of awaiter to help Imam (a.t.f.s.) The awaiter of reappearance prepares himself for helping Imam (a.t.f.s.) at the time of his reappearance. He fulfills this important responsibility by making a sincere intention from the depth of his heart in the time of occultation.
The value of intention in the performance of good deeds is highlighted by the Messenger of Allah (s.a.w.s.) thus: نيَّةُ المؤمِن خيرٌ من عمله 'The intention of a believer is better than his action'.[^7] At times a believer decides to do a good deed, but is unsuccessful in doing so. And often with respect to some good deeds he falls prey to ostentation and showoff, which affect his sincerity. Thus the intention behind the deed is very important.
As per traditions, intention of a good deed is better than the deed itself and Allah the High, due to His grace and obligation upon believer rewards him just for the intention, regardless of whether He actually performs the action.
