Intro
I wanted to post about this magazine by Mahmud Ahmad.  I will post quotes that I have found.

Quotes
“Thirdly, the fate of the people who are not aware of the teachings of the Promised Messiah is known to Allah.  It cannot be said with certainty what is in their minds.  Since the Sahriah takes cognizance of what is patent we are bound to consider them Kafirs”. (Tashhizul Azhan, April 1911, page 139).  Also quoted in Muhammad Ali’s “Heresy in Islam” (1922) see page 34.

“Thus not only the person who does not declare him Kafir but happens to ignore his call is an unbeliever, but even one who considers him truthful in his heart and does not reject him outright but is hesitant to take the pledge, is an unbeliever”. (Tashhizul Azhan, April 1911, page 141). Also quoted in Muhammad Ali’s “Heresy in Islam” (1922) see page 34.  

“It is our faith and belief that Hazrat Sahib was an apostle of God, appointed by the Lord. It is our conviction that Allah has always been sending His prophets. At the same time it is also our belief that the Holy Prophet Mohammad, is Ra’uf, Rahim, Apostle of Allah, and Khataman -Nabiyin. After him, there has been no prophet with a new Sharia ; and he is the seal for all kinds of Nabuwwat in the future. Whosoever will reach God now, he will do so only by virtue of obedience and loyalty, and devotion to him, as we read in the Holy Quran: ` ‘ `Say, if you love Allah, follow me, and God will begin to love you.’ His honour lies only in this. Can a man be called honoured who has no subordinates under him? No, really honoured and high in rank would only be one who has many people of position and power placed under him. Look at things in this world itself. Would you prefer to be a king, or an emperor? The world emperor denotes a higher position than does the word king. It carries the sense that he rules over kings. He stands higher than kings, not lower. Similarly a Nabuwwat is higher which has some prophets placed under its authority, than another Nabuwwat which has no prophet placed under it. So, on this same principle, we hold the Promised Messiah as a Nabi, and a Mamur, duly commissioned, in the light of unassailable Reports in the works of Hadith.” (Tashhizul Azhan ) Vol. 1V & VI pages 130, 131, April, 1911)

“If any one could become alive after death, after three centuries, he would see that the world is as full of Ahmadis as the sea is full of water drops.”
(Tashhidhul Adh-han, January 1913, p 39)

“The reverend says that all Muslims are agreed upon this issue, except Sir Sayyid who has rejected it on rational grounds, but that no one has rejected it on the basis of the Holy Quran. However, I will go on to show that he is wrong in saying that no one has rejected it from the Holy Quran. I will prove that people have shed light on this from the Quran itself and have proved that Jesus was not born without a father, but was born like the rest of the world. What I mean to say is that there have been differences on this issue, and that some people have believed Jesus to have had a father.”

(Tashhiz al-Azhan, April 1913, pp. 165 – 170)

“These quotations prove that except for the Promised Messiah no one else can be a Prophet…After Holy Prophet (pbuh) only one Prophet was necessary and the coming of too many Prophets would have hindered the Wisdom and Schemes of God.”

(Tasheed-ul-azhan, Qadian, No.8, vol.12, p.11 dated August 1917)
