From `Abdul-`Aziz ibn `Abdullah ibn Baz to our honorable brother, his Eminence ShaykhMay Allah guide him to good, Amen.
As-salamu `alaykum warahmatullah wabarakatuh (May Allah's Peace, Mercy, and Blessings be upon you!):
My beloved brother, your honored inquiry dated 2 Muharam, 1388 was received - may Allah guide you - referring to the opinion that clarifies the weakness in claiming that the "Wa" in His saying (Exalted be He) in Surah (Qur'anic chapter) Al-Zumar concerning the rights of the people of Jannah (Paradise): "Hatta itha ga'ooha Wa futihat Abwabuha" till, when they reach it, and its gates will be opened (before their arrival for their reception) is the "Waw Ath-thamaneya" (a conjucntion letter that joins the eighth item in a series of different countable items to the previous seven in the Qura'nic verses), this is an already known opinion, and I would like to inform your Eminence that what you have mentioned is right.
I also pointed this out while I was commenting on the Ayah, and also mentioned that the knowledgeable scholar Ibn Al-Qayyim (may Allah be merciful to him) considered confirmed the weakness of this opinion as it was deemed so by the knowlegeable scholar Ibn Kathir (may Allah be merciful with him). However, both had likely considered it to be "Waw Atf" (coordinating conjunction) but perhaps your Eminence has not noticed this; however it is very clear, and the opinion that it is "Waw Ath-thamaneya" cannot be correct by any means, either from the Shari`ah (Islamic Law) or the linguistic perspective.
As for the opinions of some exegetes such as the author of (Rawh Al-Ma`an), deeming it to be "Waw Haal" (circumstantial conjunction), they are not sound. The correct opinion is what has been previously mentioned, that it is a coordinating conjunction and the complement is omitted after His Ayah: "Fadkhluha Khaledeen" so enter here to abide therein. and would hypothetically- and Allah knows best - run as their becoming happy and glad with this, thus will say: "Al-Hamdullilah" ( Praise be to Allah)...etc.
Furthermore, the great scholar Ibn Al-Qayyim (may Allah be merciful to him) elaborated on this in his book (Hady Al-Arwaah) when discussing the doors of Heaven, and you will find attached a copy of this book for further perusal.
I would like to thank your Eminence for your vigilance and concern for knowledge, as well as adopting the most preponderant opinion with respect to this disputable opinion. May Allah grant me, you and all our brothers profound and useful knowledge, and guide us to virtuous acts, for He is Most Bountiful and Generous.
As-salamu `alaykum warahmatullah wabarakatuh (May Allah's Peace, Mercy, and Blessings be upon you!)
