I think it is safe to say that the toilet incident is definitely true. SubhanAllah, how can they treat our holy book in such a way? A guidance to mankind. They don't heed the reminder. On that day, the punishment will be so severe. We must pray for their forgiveness.
Their was a massive outcry at the way the muslims reacted to this incident. There were riots and fights. They don't seem to understand how upset and angry we feel about something like this. The Qur'an is a part of us. It's a natural human reaction to losing something so holy and sacred. And that reaction kicks in ever stronger within the muslims when the words of the lord of the Ala'min are flushed down a toilet. Did they even bother to read it first? lol.
True, Allah will preserve the Qur'an, no matter how hard they try. It is stored within the minds and the hearts of thousands.
بِالْبَيِّنَاتِ وَالزُّبُرِ وَأَنزَلْنَا إِلَيْكَ الذِّكْرَ لِتُبَيِّنَ لِلنَّاسِ مَا نُزِّلَ إِلَيْهِمْ وَلَعَلَّهُمْ يَتَفَكَّرُونَ
With clear signs and Books (We sent the Messengers). And We have also sent down unto you (O Muhammad SAW) the reminder and the advice (the Quran), that you may explain clearly to men what is sent down to them, and that they may give thought.
May Allah guide them to a way that is straight.
