As long as their Kalima is the same and they do not contradict the Quran they are Muslim. Qadiani do both which is why they are not Muslims while Shia do not ergo they are. I know this because one of my uncle is Shia, the differences are political not theological like those of the heretic qadianis.
I. Mirza Ghulam says (Extracts from Izala-e-Auham, Roohani Khazain, vol 3 pp.114-472):
1. Holy Prophet Mohammed(pbuh) did not understand the meaning of Surah AlZilzal.
2. Other Prophets have also made mistakes and lied. (Mirza trying to justify his false statements and unfulfilled prophecies - Author)
3. Hazrath Mohammad's Revelation also turned out to be wrong.
4. Revelation did not inform Hazrath Mohammad (pbuh) about Ibne Maryam, Dajjal, Khare Dajjal, Yajoog Majoog and Daabatul Ardh.
5. Braheen-e-Ahmadiyya is referred to as the Book of God in various other books by Mirza Ghulam eg. Roohani Khazain vol.22 p.502.
6. " 'Inna Anzalnaaho Qareeban min alQadian wa bil Haq anzalnaahu No doubt we have sent him (Mirza) near Qadian and with truth we have sent him'; . . . this revelation which has been published in Braheene Ahmadiyya as well, is clearly and loudly revealing that the name of Qadian is definitely mentioned in Quran or Hadith as a prophecy."
7. Names of Makkah, Madina and Qadian are mentioned with respect in Holy Quran.
8. Holy Quran is full of obscene words. {Mirza trying to justify his foul language that he used against his opponents
II. Mirza Ghulam claimed that :
1. He was the second advent of Holy Prophet Muhammad (pbuh) and better and superior than the first coming (Roohani Khazain vol 16 pp.272)
2. Holy Prophet Muhammad (pbuh) has come again in this world as Mirza Ghulam to propagate Islam. (Roohani Khazain vol.17 p.249)
3. Ahmadis should not differentiate between Mirza Ghulam and Hazrat Muhammad (pbuh) because "Anyone who differentiate between me and Mustafa (pbuh) has not seen me and not recognized me." (Roohani Khazain vol 16 pp.171).
4. Mirza's WAHI told him : "'Muhammadur Rasoolullah wallazeena ma'ahoo ashiddaohoo' ala alkuffar rohamao bainahum' in this Wahi God has named me Muhammad and Rasoolullah." (Roohani Khazain vol 18 pp.207)
1. Those who join Mirza's Jama'at becomes a SAHABI of Rasoolullah. (Roohani Khazain vol 16 pp.258-259)
2. Since Mirza Ghulam is none other than Holy Prophet Muhmmad (pbuh) himself, therefore when an Ahmadi recites KALIMA TAYYEBAH, by Muhammadur Rasoolullah he means Mirza Ghulam Ahmad Qadiani. (Kalimat al Fasl by Mirza Basheer Ahmad s/o Mirza Ghulam Ahmad Qadiani)
III. From Mirza s/o Chiragh Bibi to Jesus s/o Mary:
1. Mirza Ghulam Ahmad was the son of Chiragh Bibi but he claimed that he is Eisa Ibne Maryam. He said that at first God converted him into Maryam for two years. After two years, God made him pregnant by blowing the soul of Eisa into him; he remained pregnant for 10 months, after whcih God converted him into Eisa. This is how he became Maryam as well as Eisa ibne Maryam. (Rooahni Khazain vol 19 pp. 87-89)
IV. Mirza Ghulam Ahmad claimed that:
1. He was Maseel Maseeh that is he has certain qualities which resemled like Eisa ibne Maryam (Roohani Khazain vol 1 p. 593).

4. Jesus (Hazrat Eisa) was a habitual liar, had a habit of uttering obscenities, an alcoholic, gluttunous and a wicked person, neither a pious man nor a seeker of truth, he was a proud man and a self-conceited person who claimed divinity. (Roohani Khazain vol 9 p.387, vol.11 p.289).
5. "The fact is that Hazrat Eisa did not perform any miracles." (Roohani Khazain vol 11 p. 290-291)

7. "Hazrat Eisa had become insane due to epilepsy." (Roohani Khazain vol 9 p. 417)
8. "I wish Hazrat Eisa had not come in this world." (Roohani Khazain vol 9 p. 417)

1. "Quran is God's Book and the words of my mouth." (Advertisment dated 15th March 1897, Roohani Khazain vol 22 p. 87)
2. "I believe in my WAHI as I believe in Quran and Torah." (Roohani Khazain vol.17 p.454)
3. "The basis for our claim is not Hadith but Quran and that WAHI which comes to us. Yes in support we also quote those Hadith which are according to Quran and DO NOT CONTRADICT MY WAHI. As for the REST OF THE HADITHs, I THROW THEM AWAY LIKE A WASTE PAPER." (Roohani Khazain vol 19 p.140)
4. Bait-ul-Zikr (Mosque adjacent to Bait-ul-Fikr, the room where Mirza Ghulam used to sit and write books) is like Haram-e-Ka'aba, 'Wa man dakhalahoo kaan amina' {and whosoever enters it, is in peace}." (Roohani Khazain vol. 1 p.666-667)
5. Verse [17:1] of Holy Quran: 'Praise be to Allah, who took His Servant on the Night Journey from Masjid Haram to Masjid Aqsa', its real and literal application is the Mosque built by father of Mirza Ghulam. (Collection of Advertisement vol.3 p.286)
[PS: According to Mirza Ghulam, Quran is the words of his mouth , his Mosque is like Haram-e-Kaba and Masjid -e-Aqsa is in Qadian and not in Jerushelm.]
VI. Mirza announced:
1. "I am Adam , I am Noah, I am Abraham, I am Isaac, I am Jacob, I am Ishmael, I am Moses, I am Jesus son of Mary, I am Mohammad SAAW. . ." (Roohani Khazain vol 22, p.521)

3. I am the "Self-implanted/Self-cultivated Seedling " of the British Government. "Government should take great care regarding this SELF-IMPLANTED SEEDLING . . . . .should instruct its officers to treat ME and MY JAMA'AT with special kindness and favours. Our family has never hesitated in shedding their blood in the way of British Rulers and did not stop from laying down their lives neither do they hesitate now." (Roohani Khazain vol.13 p.350)
4. "From my early age till now when I am 65 years of age, I have been engaged , with my pen and tongue, in an important task to turn the hearts of Muslims towards the true love & Goodwill & sympathy for the British Government and to obliterate the idea of Jehad from the hearts of stupid (Muslims). " (Kitab-ul-Bariyah, Roohani Khazain vol 13 p.350)
