Quran does not support future revelation. Some time ago, I read the following by Dr Shabbir:
“.....I have written a powerful English/Urdu book HASHISH FROM QADIYAN/BARG-E HASHISH. You may read it in the www.Ourbeacon.com library.
However, please remember the simplest and instant way to demolish the Ahmadiyyat Falsehood instead of engaging in long debates.
Just read verse 4 of Surah 2.
Who are believers (Mu'mins)?
BELIEF IN THE QUR'AN, IN THE (DIVINE ORIGINATION OF) PREVIOUS REVELATIONS, AND IN THE LIFE HEREAFTER.
2:4 And those who choose to believe in what has been revealed to you (O Messenger) and the truth in what was revealed before your times. And they have conviction in the Life Hereafter.
There is NO mention of belief in any Revelation after the Qur'an until Qiyamah. Ahmadiyyat is demolished then and there.
