Was the night of Isra and Mi'raj on the twenty-seventh of Rajab?

There is no evidence that the Isra and Mi'raj occurred on the twenty-seventh night of Rajab. Scholars have differed in determining their time, and the correct view is that there is no authentic evidence for a specific date, as held by verifying scholars such as Ibn Taymiyyah, who denied that the night of Isra—even if it were known—is superior to Laylat al-Qadr (the Night of Decree).
