Check this out, very interesting findings of Dr. Tariq Al Swaidan might grasp your attention:

Dr.Tarig Al Swaidan discovered some verses in the Holy Qur'an that mention one thing is equal to another, i.e. men are equal to women.

Although this makes sense grammatically, the astonishing fact is that the number of times the
word man appears in the Qur'an is 24 and number of times the word woman appears is also 24, therefore not only is this phrase correct in the grammatical sense but also true mathematically, i.e. 24 = 24.

Upon further analysis of various verses, he discovered that this is consistent throughout the whole Qur'an, where it says one thing is like another. See below for astonishing result of the words mentioned number of times in Arabic Qur'an:

Dunia (one name for life) 115. Aakhirat (one name for the life after this world) 115
Malaika (Angels) 88 . Shayteen (Satan) 88
Life 145 .... Death 145
Benefit 50 . Corrupt 50
People 50 .. Messengers 50
Eblees (king of devils) 11 . Seek refuge from Eblees 11
Museebah (calamity) 75 . Thanks 75
Spending (Sadaqah) 73 . Satisfaction 73
People who are mislead 17 . Dead people 17
Muslimeen 41 . Jihad 41
Gold 8 . Easy life 8
Mag! ic 60 . Fitnah (dissuasion, misleading) 60
Zakat (Taxes Muslims pay to the poor) 32 . Barakah (Increasing or blessings of wealth) 32
Mind 49 . Noor 49
Tongue 25 . Sermon 25
Desite 8 . Fear 8
Speaking publicly 18 . Publicising 18
Hardship 114 .... Patience 114
Muhammed 4 . Sharee'ah (Muhammed's teachings) 4
Man 24. Woman 24

And amazingly enough have a look how many times the following words appear:

Salah 5, Month 12, Day 365,
Sea 32, Land 13

Sea + land = 32+13= 45

Sea = 32/45*100=71.11111111%
Land = 13/45*100 = 28.88888889%
Sea + land =100.00%

Modern science has only recently proven that the water covers 71.111% of the earth, while the land covers 28.889%.

Is this a coincidence?
Question is that Who taught Prophet Muhammed (PBUH) all this?
