The "Basmala بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ" consists of 19 letters.
"Basmala" appears 114 times in the Quran, a multiple of 19.
The count of chapters in the Quran is a multiple of 19.
The count of verses in the Quran is a multiple of 19.
The sum of chapters' numbers in the Quran is a multiple of 19.
The sum of all digits mentioned in the Quran is a multiple of 19.
The count of the word "Allah" in all the Quran is a multiple of 19.
The sum of all verse numbers in which the word "Allah" appears is a multiple of 19.
19 different chapters in the Quran start with letters that have no meaning at all. When we count the number of occurrences of all the letters in the Quran and give each letter a numeric value equal to its rank and then add the numeric values of those letters we get a multiple of 19. The most used letter is (ا) and we give it a value of 1. The second most used letter is (ل) and we give it a value of 2... Then we add the numeric value of those letters we get a multiple of 19 (361=19x19). So if anyone changed a single word containing those letters in the Quran the signature would have been broken. (YouTube in Arabic.)
God says that He assigned 19 angels to guard Hell, and He made their count "19" so that believers shall increase their faith.
(In the Christian Bible Jesus insists that the only sign we should verify is him being in the grave for three days and three nights (Matthew 12:38-40). So we are checking: He was crucified on Friday afternoon, the day before the Sabbath (Mark 15:42) and then he was resurrected on Sunday morning (Mark 16:9). Between Friday afternoon and Sunday morning there is 36 hours. Can anyone fit within those 36 hours three days and three nights?)

shaykh ibn baaz(rahimahullaah) about this so called miracle ofof number 19, and he hashas this to say;

This study is among the fabricated falsities of a sect called Al-Batiniyyah Al-Baha’iyyah. It is based on glorifying the number 19. There is no doubt that this study is false, as it involves manipulating the Glorious Qur’an and distracting people from pondering its true meanings.

This malicious group holds many false beliefs such as some of its leaders claiming prophethood.
Its followers believe in Hulul (a Sufi term meaning indwelling) and Ittihad (a Sufi claim of union with Allah), deem Jihad (fighting in the Cause of Allah) to be unlawful and call for the unification of religions plus many other things.

So, it is the duty of Muslims to beware of falling into this evil group and of being affected by its ideas or books.

We ask Allah (Glorified and Exalted be He) to save us from their plotting and to protect Muslims from their evils, for He is All-Powerful.

May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
