Does Laylat al-Qadr change each year to a different time, such that one year it might be on the 27th night and the following year on the 23rd night? And is it true that the Prophet, peace and blessings be upon him, did not know its exact time?

Verified scholars hold that Laylat al-Qadr (the Night of Decree) shifts within the last ten nights of Ramadan. Most scholars believe it is an unspecified night among the last ten, with the odd nights being the most likely, such as the twenty-seventh, twenty-third, or twenty-first night.

However, the verified scholars stated that it shifts, meaning it might be the twenty-seventh night in one year, the twenty-third night in another year, and the twenty-first night in yet another year. This opinion is more evident, and it reconciles the various hadiths. This is the view of Malik, Al-Thawri, Ahmad, Ishaq, Abu Thawr, and others.

The most preponderant opinion is that it shifts, as understood from the hadiths related to this topic.
