Imam Sadiq (pbuh):

Laylat al-Qadr1 is the heart of Ramathan2.

Heart is [the core of] existence!

It produces pulse

Yes, Laylat al- Qadr produces the pulse of Ramathan

Likewise, Imam Zaman (mgehr)3 is the heart of existence.

He sets and compiles, all the dispersed components of the universe.

So, Laylat al-Qadr is the heart of Ramathan month.

۱-     Laylat al-Qadr in Islamic belief, is the night when the first verses of the Quran were revealed to the Islamic prophet Muḥammad. It is one of the nights of the last ten days of Ramathan. Muslims believe that on this night the blessings and mercy of God are abundant, sins are forgiven, supplications are accepted, and that the annual decree is revealed to the angels who also descend to earth.

۲-     Ramathan is the ninth month of the Islamic calendar, and is observed by Muslims worldwide as a month of fasting  to commemorate the first revelation of the Quran to Muḥammad according to Islamic belief.

۳-     Imam Zaman (mgehr) is one of Imam Mahdī (mgehr)’s titles which means, he has power of guidance in their time on the creatures.
