In this explanation of Aqeedah Tahawiyyah, brother Dawud Burbank explains the Point #5 ,#6 and #7 as outlined below.
5. And there is nothing worthy of worship except Him.
This is Tawheed Al Uloohiyyah. Laa Ilaah means nothing worthy of worship except Him. But if you said, “Nothing is worshiped except Him”, then this is false, because there are many that are worshipped other than Allaah the Glorious and Majestic. So if you say that nothing is worshipped except Allaah, you have made everything that is worshipped into Allaah, and this is the Madh’hab of the people of Wahdatul Wajood, so if the one who says that believes in it, then he is from the people of Wahdatul Wajood, but if he does not believe in it, then he said blindly following someone, or because he heard it from someone, then this is incorrect, and it is obligatory upon him to correct that, and some people start their Salaah with this, “Nothing is worshipped except You.” And Allaah is the One Who has the right to be worshipped, and anything else other than Him that is worshipped, is worshipped upon falsehood. He the most High says, “That is because Allaah, He is the Truth, and what they invoke besides Him, it is falsehood, and verily, Allaah He is the Most High, the Most Great.” (Al Hajj 22:62)
6. He is Qadeem (Eternal) with no beginning, and the Ever Lasting with no end.
As the statement of Allaah proves this, “He is the First and the Last.“ (Al Hadid 57:3), along with the statement of His Messenger sallallaahu alaihi wa sallam, “You are the First, so there are none before You, and You are the Last, so there are none after You.” 
But the word Qadeem (old) is not associated with Allaah, except informatively. It is not from His names; rather from His names is Al Awwal (The First), and Al Awwal is not like Al Qadeem, because Al Qadeem may have something before it, while Al Awwal has nothing preceding it. He sallallaahu alaihi wa sallam said, “You are Al Awwal, so there are none before You.”
Rather, the author was cautious, so he said, “ He is Qadeem with no beginning.” But if he would have said, “Qadeem” and stopped, then the meaning of this would be incorrect.

7. He will not perish, nor will He pass away.
Perishing and passing away hold the same meaning. Allaah has been characterized with an everlasting life; He the most High says, “And put your trust in the Ever Living One Who dies not, and glorify His Praises, and Sufficient is He as the All-Knower of the sins of His slaves.” (Al Furqaan 25:58). So extinction does not come to Allaah, and He the Glorious and Most High says, “Everything will perish save His Face. His is the Decision, and to Him you shall be returned.” (Al Qasas 28:88). And He the most High says, “Whatsoever is on it will perish. And the Face of your Lord full of Majesty and Honor will abide forever.” (Ar Rahman 55:26-27). So eternity is for Allaah, and the creation will die and then be summoned, and they used to be non existent in the beginning, and then Allaah created them, and then they will die, and then Allaah the Glorious and Majestic will summon them. So Allaah the most High has no beginning, nor an end.
