Shiavault - a Vault of Shia Islamic Books Mikyalul Makarim Fee Fawaaid ad-Duaa Lil Qai’m vol. 2 69-70: Not To Fix The Time Of Reappearance And To Falsify Those Who Fix The Time Divine wisdom has kept the time of the reappearance of Imam (as) a secret because its effect is connected to Allah. As mentioned in the supplication of Imam (as) related by Shaykh Amri: “O Allah! You know the time of Your Wali’s reform (reappearance) without being taught.
So issue the command that he may reappear lifting the curtain of Ghaibat. Bestow me the Taufeeq of patience with regard to Intezar. So that I do not prefer advancement while you had postponed it. And that I do not incline towards delay on matters that You expedite. And that I do not prefer the exposing of all things that You have hidden. And that I do not strive to find the things You have concealed.
And that I do not oppose You regarding the decrees of the universe whose hidden wisdom is known to you.” In the book of Husain bin Hamadan through the author’s own chain of narrators it is mentioned from Mufaddal bin Umar that he said: I asked Imam Sadiq (as) regarding the verse: يَسْأَلُونَكَ عَنِ السَّاعَةِ أَيَّانَ مُرْسَاهَا ۖ قُلْ إِنَّمَا عِلْمُهَا عِنْدَ رَبِّي ۖ لَا يُجَلِّيهَا لِوَقْتِهَا إِلَّا هُوَ ۚ ثَقُلَتْ فِي السَّمَاوَاتِ وَالْأَرْضِ ۚ لَا تَأْتِيكُمْ إِلَّا بَغْتَةً ۗ يَسْأَلُونَكَ كَأَنَّكَ حَفِيٌّ عَنْهَا ۖ قُلْ إِنَّمَا عِلْمُهَا عِنْدَ اللَّهِ وَلَٰكِنَّ أَكْثَرَ النَّاسِ لَا يَعْلَمُونَ They ask you about the hour, when will be its taking place?
Say: The knowledge of it is only with my Lord; none but He shall manifest it at its time; it will be momentous in the heavens and the earth; it will not come on you but of a sudden. They ask you as if you were solicitous about it. Say: Its knowledge is only with Allah, but most people do not know.
(Qur’an, Surah Araaf 7:187) And the verse: فَهَلْ يَنْظُرُونَ إِلَّا السَّاعَةَ أَنْ تَأْتِيَهُمْ بَغْتَةً ۖ فَقَدْ جَاءَ أَشْرَاطُهَا ۚ فَأَنَّىٰ لَهُمْ إِذَا جَاءَتْهُمْ ذِكْرَاهُمْ Do they then wait for aught but the hour that it should come to them all of a sudden? Now indeed the tokens of it have (already) come, but how shall they have their reminder when it comes on them?
(Qur’an, Surah Muhammad 47:18-19) And the verse: اقْتَرَبَتِ السَّاعَةُ وَانْشَقَّ الْقَمَرُ The hour drew nigh and the moon did rend asunder. (Qur’an, Surah Qamar 54:1) And the verse: وَمَا يُدْرِيكَ لَعَلَّ السَّاعَةَ قَرِيبٌ.
