Usama Dakdok on Surah 12 Part J

Revealing the Truth About Islam starts with the news Muslims are making around the world. Then Usama turns to Surah 12 verse 81. The sons of Jacob are talking to their father about one of their brothers having stolen. Why did the brothers not tell the whole story? Did they think their father who was not with them knew it all, or did they simply forget the detail just written about? So many questions!

Muslims do you dare to answer any of these questions? Does this chapter prove it is impossible to read the Quran without turning to the Bible for answers?
