Salam...
I took this from Zakir Naik and typed it up...
Go through the following process to defeat the atheist...
Da3wah to an Atheist:
Most of the atheists are atheists because they believe in Science and Technology. They think that science has advanced so much that we don’t require any scripture, religion, etc.
The first question to ask them is…
1) Let’s suppose there is an equipment, there is a machinery, which no one in the world has seen before… if it’s brought in front of you (the atheist), and if we ask the question to the atheist, “Who will be the first person who will be able to tell you the mechanism of this machinery, of this object?” What can his reply be? They will reply, “The first person who will tell you the mechanism of this machinery is the manufacturer (some may say the creator - some may say the inventor – some may say the producer) (whatever they say it will be somewhat similar – just keep it at the back of your mind). Then ask them the next question…
2) “How did our universe come into existence?” The atheist will tell us that “initially there was a primary nebula; then there was a big bang, which gave right to galaxies, the sun, the moon, and the earth on which we live. This is what we call as the big bang.” Ask them, “When did you come to know about this (the big bang)?” They will tell you, “about 30-40 years back, the scientists discovered this.” You tell him, “But what you’re talking about, the big bang, is already mentioned in the Quran: in surah Al-Anbiya’, chapter #21, verse #30. Which means “Do not the unbelievers see; the heavens and the earth were joined together, then We parted them.” What they are talking about, the big bang, was already mentioned in the Quran 1400 years ago. Ask them, “Who could have mentioned that?” The atheist will say “maybe it’s a fluke (luck).” No problem. Don’t argue with him.
3) The light of the moon. Is it its own light or reflected light? The atheist will say that “previously we thought that the moon had its own light. Recently (100-200 years back) we have come to know that the light of the moon is not its own light but a reflected light. The Quran mentioned this 1400 years ago: In surah Al-Furqan, chapter #25, verse #61. Which means “Blessed is He who has placed a constellation in the sky; and placed therein a lamp, a sun, having its own light; and moon, having a reflected light, a borrowed light.” Who could have mentioned in the Quran 1400 years ago that the light of the moon is not its own light, but a reflected light, which we have come to know recently? The atheist may say, “your prophet Muhammad (peace be upon him), maybe he was an intelligent man.” Don’t argue with him, continue.
4) The world that we live on. What’s the shape of this earth on which we live? The atheist will tell you that it is spherical. Ask him, “when did we come to know?” He will tell us that “it was 1597 when Sir Francis Drake sailed around the earth and proved that the earth was spherical.” The Quran says 1400 years ago in surah An-Nazi3at, chapter #79, verse #30. Which means “And thereafter We have made the earth egg-shaped.” The Arabic word Dahaha (in this verse) is not referring to a normal egg, on the other hand it is referring to the egg of an ostrich. And we know the earth is not completely round like a ball, but it is geo-spherical in shape; it is flattened from the poles (vertically). If you analyze the egg of an ostrich, that too is geo-spherical in shape. Who could have mentioned 1400 years ago that the shape of the earth is geo-spherical? Again the atheist may say, “You know, your prophet, maybe he’s super intelligent.” Don’t argue with him. Just continue.
5) Very recently (~1982) scientists thought that the sun was stationary – it revolved but did not rotate about its own axis. However, in the Quran, 1400 years ago, in surah Al-Anbiya’, chapter #21, verse #33. Which means, “It is Allah who has created the night and the day, the sun and the moon, each one travelling in orbit with its own motion.” So the Quran says that besides the sun just revolving, it even rotates about its own axis. Who could have mentioned this in the Quran 1400 years ago? The atheist will be silent. There will be a long pause. Don’t wait for their reply. Keep on continuing.
6) Today science tells us that the universe is expanding. Which is mentioned in the Quran 1400 years ago in surah Adh-Dhariyat, chapter # 51, verse #47.
7) The Quran speaks about the water cycle. The water cycle was first described in 1580. How the water evaporates from the ocean, forms into clouds, moves into the interior, falls down as rain. This water cycle is spoken about in great detain in the Quran in several verses:
-In surah Az-Zumar, chapter #39, verse #21
-In surah Ar-RÛm, chapter #30, verse #24
-In surah Al-Hijr, chapter #15, verse #22
-In surah Al-Mu’minun, chapter #23, verse #18
-In surah An-NÛr, chapter # 24, verse #43
-In surah Ar-RÛm, chapter #30, verse #48
-In surah Al-A’raf, chapter #7, verse #17
-In surah Al-Furqan, chapter #25, verse #48-49
-In surah Fatir, chapter #35, verse #9
-In surah Ya-Sin, chapter #36, verse #34
-In surah Al-Mulk, chapter #67, verse #30
-In surah At-Tariq, chapter #86, verse #11
There are hundreds of verses in the Quran that speak about the water cycle which science has discovered recently. We can keep on talking, continue.
8) Today we have come to know that plants have got sexes, which we did not know earlier. Which the Quran says 1400 years ago in surah Ta-Ha, chapter #20, verse #53; that the plants have got sexes: male and female.
9) Today we have come to know that there are two types of waters: sweat and salty. And there is a barrier between them. Which is mentioned in the Quran in surah Al-Furqan, chapter #25, verse #53. And surah Ar-Rahman, chapter #55, verse #17-18. Which means, “It is Allah who has let free two bodies of flowing water; though they meet, they do not mix – there is a barrier between them.
10) Today science tells us that it is the mountains which prevent the earth from shaking. Which is mentioned in the Quran 1400 years ago in surah An-Naba’, chapter #78, verse #6-7.
11) The Quran speaks about Biology. Its says what means that “We have created every living creature from water – every living thing. In surah Al-Anbiya’, chapter #21, verse #30. The Quran mentioned this 1400 years ago.
12) The Quran speaks about Zoology. About the lifestyle of the spider in surah Al-‘AnkabÛt, chapter #29, verse #41.
13) About the ant in surah An-Naml, chapter #27, verse #17-18.
14) About the bee in surah An-Nahl, chapter #16, verse 68-69.
15) The Quran speaks about embryology in surah Al-‘Alaq, chapter #96, verse #1-2. Which means, “We have created the human being from ‘alaqah, a leach-like substance – which we have come through recently.
16) The Quran speaks about embryological stages in surah Al-Mu’minun, chapter #23, verse #12-14.
We can go on talking about the scientific points. There are more than 1000 verses in the Quran which speak about Science. After every scientific fact you ask the question, “Who could have mentioned that in the Quean?” The only reply the atheist can give you is, “the Creator, the Cherisher, the Manufacturer, the inventor, the Producer.
This Creator, this Manufacturer, this Producer, this Inventor; we muslims call Him as Allah.
That is the reason why Francis Bacon, a very famous philosopher said, “Little knowledge of Science takes you away from Almighty God. In-depth knowledge of Science makes you a believer in God.”
That is the reason scientists today are not eliminating God – they are eliminating models of God.
La’ilaha’illAllah!
