Assalaamu alaykum. My aunt told me that there are two verses on Tanzil.net that are written wrong in Arabic. Here are the two that she discovered: http://tanzil.net/#2:126 http://tanzil.net/#2:144 Could you please look over the entire Surahs in this website?
All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
We would like to thank you for contacting us and we commend your keenness and zeal for the preservation of the Quran against any print errors. May Allaah bless you for that.
Your aunt is right about the two verses; they are written wrong in Arabic. You can contact the people in charge of the website and share this information about the mistakes with them so that they would correct them.
Allaah knows best.
