Every letter in the Arabic alphabet has a numerical (gematrical) value. In other words, in Arabic every letter stands for a number. A number of calculations can be made from this basis. These are referred to as numerological (abjad) calculations or "hisab al-jumal."239Muslims who took advantage of the fact that every letter of the alphabet represents a number have used this in a number of fields. Ilm'ul Jafr is one of these.

Jafr is the science of foretelling what is likely to happen in the future. One of the methods employed by people who engage in this is to compare symbolic forms and letters' numerological values. The main difference between "abjad" and "jafr" methods is that the former refers to what has already taken place and the latter to what is likely to take place in the future.240
This method of calculation is a form of writing which goes back several centuries and which was widely used before the revelation of the Qur'an. Everything which happened in Arab history was written down by attributing numerical values to letters thus the date of every event was recorded. These dates were obtained by adding up the particular numerical values of every letter employed.
When certain verses of the Qur'an are examined in the light of the "abjad" method, we see that a number of dates emerge which are fully in accordance with the meanings of those verses. When we see that things referred to in these verses actually happened on the dates obtained by this method, we understand that there is a secret indication regarding those events in the verses. (Allah knows best.)
The 1969 Moon Landing is Indicated in the Qur'an

The Hour has drawn near and the moon has split. (Qur'an, 54:1)
The Arabic word "inshaqqa" (split) used in the above verse is derived from the word "shaqqa," which can also be used to mean "causing something to rise, ploughing or digging the soil":

We pour down plentiful water, then split the earth into furrows. Then We make grain grow in it, and grapes and herbs and olives and dates and luxuriant gardens and orchards and meadows.
(Qur'an, 80:25-31)
As we can see, the word "shaqqa" in the above verse is not being used in the sense of "dividing into two" but of "slicing through the soil, reaping various crops." When evaluated in this sense, the meaning of the word "shaqqa" in the expression "the moon has split" (Qur'an, 54:1) can also be seen to be referring to the 1969 moon landing and the studies performed on the moon land. (Allah knows best.) In fact, there is another very important indication here: Some of the "abjad" values of certain words in this verse in Surat al-Qamar also point to the figure 1969.
One important point which needs to be stressed in this method of calculation is the likelihood of producing very large or irrelevant numbers. Despite the probability of a relevant number emerging being exceedingly small, it is striking that such a clear figure should result.
The Hour [has drawn near] and the moon has split.

Hijri: 1390, Gregorian: 1969
In 1969, American astronauts carried out research on the Moon, dug the soil up with various pieces of equipment, split it and carried specimens back to Earth.
We must, however, make it clear that the splitting of the Moon is of course one of the miracles given to our Prophet (saas) by Allah. This miracle is revealed thus in a hadith:
The people of Mecca asked Allah's Apostle to show them a miracle. So he showed them the moon split in two halves between which they saw the Hiram' mountain. (Sahih Bukhari)
The above miracle is the splitting of the Moon revealed in the verse. However, since the Qur'an is a Book that addresses all times, one may think of this verse as referring to the exploration of the Moon in our own day. (Allah knows best.)
