5.Imam Mahdi (ajtfs) related Invocation after Dhuhr Prayers
Among the most recommended times for invoking the early reappearance of our master, Imam-e-Asr (a.s.) is after Dhuhr prayers.
According to one tradition from Imam Sadiq (a.s.),“One who says the following after the morning and noon prayers will not die till he reaches to the Qaem (a.t.f.s.) of Ale Muhammad (s.a.w.a.).”,
6. The Invocation “ يَا سَامِعَ كُلّ صَوْتٍ ” after Dhuhr prayers:'
Following in the footsteps of Imam Sadeq (a.s.), we should pray for
Imam al-Mahdi (a.t.f.s.), the saviour of humanity, who will reappear
in the last era as promised by the Messenger of Islam (s.a.w.a.) to
his nation through authentic traditions. Abbaad Ibn Muhammad al-
Madaaeni says, “I went to meet Imam Sadeq (a.s.) in Madina. After
finishing his zohr prayers, he (a.s.) raised his head towards the sky and said,
allahumma inni as'aluka alyusra ba`da al`usri
O Allah, I surely beseech You for easiness after difficulty,
وَٱلْفَرَجَ بَعْدَ ٱلْكَرْبِ
walfaraja ba`da alkarbi
relief after misfortune,
وَٱلرَّخَاءَ بَعْدَ ٱلشِّدَّةِ
walrrakha'a ba`da alshshiddati
and comfort after hardship.
اَللَّهُمَّ مَا بِنَا مِنْ نِعْمَةٍ فَمِنْكَ
allahumma ma bina min ni`matin faminka
O Allah, You are certainly the source of each and every favor that covers us.
لاَ إِلٰهَ إِلاَّ أَنْتَ
la ilaha illa anta
There is no god save You.
أَسْتَغْفِرُكَ وَ أَتُوبُ إِلَيْكَ
astaghfiruka wa atubu ilayka
I pray Your forgiveness and repent before You.
5. Imam Ja`far al-Sadiq (peace be upon him) is reported as saying: Anyone who implores Almighty Allah’s forgiveness (i.e. astaghfirullaha) seventy times after the `Asr Prayer will have seven hundred of his sins forgiven.
6.Imam Muhammad al-Taqi (al-Jawad) (peace be upon him) is also reported as saying: Anyone who recites Surah al-Qadr (No. 97) ten times after the `Asr Prayer will be granted the reward of the deeds of all creatures on that day.
10. Invocation of Imam Kazim (a.s.) after Asr prayers for the Reappearance of Imam-e-Zamaan (a.t.f.s.)
It was stated in "Falaahi Ssa'il" among the important supplication to be observed after (Asr) afternoon prayer by imitating our master Musa ibn Ja'afar Al-Kazim (peace be upon him) in his dedicated supplication to our master Al-Mahdi
(peace and blessing of Allah be on his grand father Muhammad and same to him) as it was narrated by Yahya bn Al-Fadl Naufali, he said: I entered to Abu Al-Hasan, Musa bn Ja'afar after (Asr) afternoon prayer in Baghdad, thus I met him raising his hand to the Heaven and I heard him reciting the following:
I said to him, whom did you prayed for? He said: to Al-Mahdi of the Prophet's household (peace be on them).
He continued saying: may my father be sacrifice for him, his eyebrow are very close, his legs are very energetic, his shoulder is wide, brown in colour and close to be yellowish, may my father be sacrifice for him, his night shall guard the stars by his bowing down and prostration to Allah, may my father be sacrifice for him, he who the blames of those that blame shall not affect before Allah, he is the luminous lamp, may my father be sacrifice for him, he shall rise with the command of Allah.
I said to him, when will he come out? He said: when you saw armies from the city of Anbar in Iraq at the beach of Furat, sirah and Dajlah, and the arch of Kufah is destroy, and burning of some houses in Kufah, when you see all this, verily Allah will act according to His wish, no one can subdue the commandment of Allah and no one can review His Judgement.
