To learn about Islam is important whether you are a Muslim or not, since 25% or 1.5 billion of the world’s population is Muslim. All the media interest in Islam with the “war on terror” to get the correct information is important. Website from non-Muslim sources vary from the outright offensive to the factually incorrect only Islamic websites by Muslims can give the true picture.
The information in these sites must be backed up by the Quran and Hadiths. The Quran is the word of Allah(swt) as given directly or by angel Jibril (gabril)(AS) to the last and final seal of the prophets Muhammad (pbuh).
As the verses were revealed the prophet Muhammad(pbuh) would recite them to his companions who would memorise them and also write them down and distribute them among the muslim community.
So the Quran is the recorded word of Allah(swt) directly from the messenger of Allah(swt) the prophet Muhammad(pbuh) and there is only one version of the Quran with not a single word altered since the revelation to the present day.
The Hadiths are saying and /or actions of the prophet Muhammad (pbuh) which were witness by the companions of the prophet Muhammad(pbuh) and then written down for record. Since muslims believe that the prophets of Allah(swt) are pure and innocent, for Allah(swt) would only choose the best among mankind who were tested in their lives to lead people who had gone astray and bring them to the right path.
Say (O Muslims), “We believe in Allah and that which has been sent down to us and that which has been sent down to Ibrahim (Abraham), Isma’il (Ishmael), Ishaq (Isaac), Ya’qub (Jacob), and to Al-Asbat [the offspring of the twelve sons of Ya’qub (Jacob)], and that which has been given to Musa (Moses) and ‘Îsa (Jesus), and that which has been given to the prophets from their Lord. We make no distinction between any of them, and to Him we have submitted (in Islam).”
( Quran Al-Baqara, Chapter #2, Verse #136).
These hadiths were then checked by Imams as how many people were present when the prophet Muhammad said or did an action, was the hadith backed up by all present, what was the character of the companions present so the narration of the hadith strong or weak.
Only when many checks were made that the hadiths considered authentic. The most comprehensive collection of hadiths are found in the books of Imam Bukhari, Muslim, Tirmidhi, Nasa’i, Abu Dawud and ibn Majah (may Allah(swt) be pleased with them all).
You can only make a judgement by the information you have and if that is incorrect then the judgement is most defiantly wrong. The judgement of your faith is for your eternal soul and on the day of Judgement in the court of Allah(swt) every smallest deed good and bad will have to be accounted for.
No one will have an excuse to plead ignorance, as in the Quran Allah(swt) says He sent messengers to many nation
Verily, We sent (Messengers) to many nations before you (O Muhammad (pbuh)). And We seized them with extreme poverty (or loss in wealth) and loss in health (with calamities) so that they might humble themselves (believe with humility).
( Quran Al-Anaam, Chapter #6, Verse #42).
