An amazing numerical phenomenon in the Qur’an!
The Qur’an speaks about the youth of the cave in Surat Al-Kahf (Chapter 18 – The Cave). In their pursuit to preserve their faith and to continue living as believers, they seek refuge in a cave thereby receiving care and protection from Allah.
Allah says that the youth of the cave remained in there for 300 and an extra 9 years.
ثُمَّ بَعَثۡنَـٰهُمۡ لِنَعۡلَمَ أَیُّ ٱلۡحِزۡبَیۡنِ أَحۡصَىٰ لِمَا لَبِثُوۤا۟ أَمَدࣰا
Then We awakened them that We might show which of the two factions was most precise in calculating what [extent] they had remained in time.
[18:12]
وَلَبِثُوا۟ فِی كَهۡفِهِمۡ ثَلَـٰثَ مِا۟ئَةࣲ سِنِینَ وَٱزۡدَادُوا۟ تِسۡعࣰا
And they remained in their cave for three hundred years and exceeded by nine.
[18:25]
قُلِ ٱللَّهُ أَعۡلَمُ بِمَا لَبِثُوا۟ۖ لَهُۥ غَیۡبُ ٱلسَّمَـٰوَ ٰتِ وَٱلۡأَرۡضِۖ أَبۡصِرۡ بِهِۦ وَأَسۡمِعۡۚ مَا لَهُم مِّن دُونِهِۦ مِن وَلِیࣲّ وَلَا یُشۡرِكُ فِی حُكۡمِهِۦۤ أَحَدࣰا
Say, “Allah is most knowing of how long they remained. He has [knowledge of] the unseen [aspects] of the heavens and the earth. How Seeing is He and how Hearing! They have not besides Him any protector, and He shares not His legislation with anyone.”
[18:26]
In the same qur’anic passage, there are exactly 309 words between the first and final mention of the word ‘remained’. And exactly 9 words between the word, 300, and the final mention of the word ‘remained’.
