Imam explains the matter in his famous book "combat with the self" as following:
According to the order of the Holy Apostle, peace be upon him and his progeny, (which is related in one of his sermons) all of the servants of God, the Supreme, have been invited by Him to a feast in the blessed month of Ramadan and are to be the guests of the Provider at His feast. He says there: “O you people! The month of Allah is approaching you…and you have been invited in it to the feast of Allah.”
You have been invited during this honorable month to the banquet of God the Almighty, “and you have been invited in it to the feast of Allah,” so, get yourself ready for the magnificent feast of the Almighty.
Some traditions narrated by the holy prophet of Islam and his infallible successor says al Qadr occurs in the last ten nights of the holy month of Ramadan during an odd night. The traditions also indicate that individual and collective destinies are decreed during this holy period.
The night commemorates the period when God the Almighty revealed the sacred scripture of holy Quran to honorable prophet of Islam.
The great Imam also recommended the youth to undertake serious efforts for purification of their hearts and souls during these sacred days and nights.
We bring some phrases from Imam’s messages regarding the blessed month of Ramadan and Laylat al Qadr as following:
In the month of Ramadan, an event has taken place whose dimensions and essence is shrouded in ambiguity until eternity for the likes of us and that event is the revelation of the Qur'an. Revelation of the Qur'an in the heart of the Prophet of God on the night of Ordainment; the manner of the descent of the Qur'an and how it happened and how the Trusted Holy Spirit revealed it in the heart of the Prophet while on the other hand God commands that," Verily, we have revealed the Qur'an on the night of Qadr." (The Holy Quran, 97:1) What was the manner of revelation in the heart of the Prophet on" Laylatul Qadr"? I must say that except for the honorable Prophet himself and those that were reared in the bosom of the honorable Prophet and enjoyed the exclusive favors of the blessed and Almighty God, for others the question of its revelation is absolutely shrouded in ambiguity. What is revelation in the heart; what is the Holy Spirit; in what manner the Holy Spirit along with the Qur'an penetrated the heart of the Prophet of God; what is Laylatul Qadr?
Qur'an is that blessing of an invitation to the Prophet of God to a feast that is laid out from the beginning until eternity. The honorable Prophet benefited from it and its preliminaries are those for which he underwent long years of spiritual self abstinence until he reached the point where he merited the feast the important aspect being shunning the world. (Sahifeh-ye-Imam. V. 17, P 452-454)
Reciting Quran and comprehending its deep concept bears great divine rewards and bring about bounties and blessings.
Imam advised believers to accept responsibilities of blessed month of Ramadan
Cut yourselves off from the Satans among humans and the jinn, although we ourselves apparently cannot aspire to reaching such a valuable state of felicity.
