9.1. The Ranks of the Night of Power (Lailatul-Qadr)
It may be derived from some of the traditions that there are ranks and degrees for the Night of Power and each one of the nights of 19th, 21st, 23rd, and 27th may be considered possessing one of those degree. And the night which possesses the most superior distinction, has been mentioned in the Holy Qur'an as equal to thousand months, and whatever is destined in that night wouldn't be changed is the night of 23rd of the Holy Month, which is also known as the Night of Juhanni. And the one who wants that his actions should be exact and precise, better be vigilant during all these four nights. Of course, regarding the Night of Power there are some other narrations as well, but since their authenticity is not confirmed, it would not be appropriate to describe them here.
 Abu Yahya 'Abdullah bin Onais al-Juhanni: a shepherd from the tribes of Juhan arrived before the Holy Prophet [s] and said: 'O' Prophet of Allah! I wish you order me, so that during one of the nights of Ramadhan I come to Madina and offer the prayer.' The Holy Prophet [s] called him on the 23rd night of Ramadhan, and therefore this night become famous as the Night of Juhanni.
