Tonight is شب قدر (shab-i qadr, “the Night of Power”), the night when tradition says that the first Qurʾānic revelation was given to Muhammad. If you are interested, I hope you will enjoy my post on this subject from last year.
At some point during the final ten nights of Ramadan, Muslims observe the Night of Power (لَيلة القَدر, laylat al-qadr, in Arabic), the night when Muhammad is said to have received the first Qur’anic revelation in the year 610. To read much more about the night and that first revelation, check out my Arabic blog. I’m not going to repeat all that here; this entry is just to note the Persian name for the Night: شَبِ قَدر (shab-i qadr). “Night,” which is لَيلة in Arabic, is شَب in Persian.
