It was on December 1988 when Imam Khomeini gifted a valuable book, Sahifah Sajjadiyah, to his grandson Seyyed Ali Khomeini.
Imam called the book which contains supplications by of the fourth infallible Imam and a truthful successor of the holy prophet of Islam, a perfect example of the ascending Quran.
Imam resembled supplications attributed to Imam Zayn al-'Abidin (‘a) as ascending holy scripture.
Hojjat al-Islam Seyyed Ali Khomeini was a child at that time. The text of the Imam's donation letter reads as follows:
And I have dedicated this precious book to my beloved grandson, in whose forehead I see light and light upon light, and to the beloved one who is the memory of Ahmad, and from the pure lineage of the pure Imams (‘a).
The complete Sajjadiyah is a perfect example of the ascending Quran and is one of the greatest mystical prayers.
It is a divine book that originated from the source of the light of Allah and teaches us how infallibles used to pray God Almighty.
It is a noble book that expresses the divine knowledge, like the style of the Holy Quran, but in the style of prayer and supplication for those thirsty for divine wisdom.
