The date that appears above the inscription in the lower image is AH (anno hegirae) 1301, which is the equivalent to AD 1884.

To do the calculation, take the AH year, multiply by 0.97, and then add 622 to the result. In this case, you get 1883.97 which can be rounded to the next whole number.

The bases of the conversion are:
1. Muslims measure their era from the date of the Hegira (the Prophet's flight from Mecca to Medina in the year AD 622.
2. The factor of 0.97 is, for common purposes, an accurate and convenient way of adjusting from the Islamic lunar to the Gregorian solar year.
