1) In a number of manuscripts the letter alif is written in an incorrect way
2) There are some differences in the numbering of verses in some surah’s (chapters of the Qur’an)
3) In 2 or 3 sheets he has found the surahs are written in an alternative order to that of the standard Quran
Before I start to discuss his claims, it must be noted that Dr. Puin himself mentions that these discrepancies are minor and they would not probably lead to any sudden and significant advances in the filed of Qur’anic studies.
