1. What does the letter “Saad ص” in Qur’an mean? And is it a river in Paradise?

2. There is a Hadith which is narrated from Prophet Abraham (a.s): (Here [in this place] shall grow a tree like the tree of Adam (a.s) in the Garden of Eden)
After your permission, I have written the following on the forum …… Please clarify. Isn’t this a proof that there is a person who will be born in the End Times and will be present in that place – the place where the two rivers meet (The Righteous Servant) – and his story is well known and it is a clear reference to Imam Ahmed Alhasan (a.s) by the link to the tree of Adam … And according to the interpretation, the tree of Adam is a symbol for the knowledge of Muhammad and the Family of Muhammad (a.s) as they (a.s) narrated. And it is the tree which Allah made forbidden to the Prophet Adam (a.s) in the Garden of Eden.
