From their own words let us see how this deviant sect has managed to twist the meaning of the Kalimah, one of the foundation stones of Islam, and use it to replace and supecede the Prophet Muhammed’s(SAW) unique place in it:
“As a result of the birth of the promised Masih (the Qadiani Mirza) a difference has cropped up (in the meaning of the Kalimah). Before the birth of the promised Masih (the Qadiani Mirza) in the world as a prophet, the words Muhammad ur Rasul Allah) included in their meaning only such prophets as had preceded him; but after the incarnation of the promised Masih (the Qadiani Mirza) in the world as a prophet, one more prophet has been added to the meaning of Muhammad ur Rasul Allah. Therefore on account of the incarnation of the promised Masih the Kalimah, God forbid, does not become abolished; it rather shines more brightly. In short, the same Kalimah is (effective) even now for embracing Islam, with the only difference that the incarnation of the promised Masih (Mirza Qadiani) has added one more prophet to the meaning of Muhammad ur Rasul Allah”. (Kalimatul Fasl, page 158, by Mirza Bashir Ahmad Qadiani).
In short, the Qadiani Religion has retained the same words of the Kalimah but the Qadiani belief has changed the meaning of the Kalimah. In the Kalimah of the Muslims Muhammad ur Rasul Allah means Muhammad of Arabia (SAW) but in the Qadiani Kalimah Muhammad ur Rasul Allah means Mirza Qadiani as Muhammad incarnate, reborn in the world as a prophet for the second time. Thus it is said:
"Moreover, even if we accept by supposing the impossible that the sacred name of the gracious Prophet has been included in the sacred Kalimah because he is the last of the Prophets, even then there is no harm and we do not need a new Kalimah because the promised Masih is not a separate entity from the gracious Prophet as he (Mirza) himself says: “My being is exactly the being of Muhammad ur Rasul Allah”. Also, “One who discriminates between me and Mustafa has neither recognized me nor seen me”. And the reason for this is Allah Almighty’s promise that He would reincarnate “Khatam un Nabieen” in this world once more as a prophet as is evident from the verse “And others of them… Thus the promised Masih (Mirza of Qadian) is himself Muhammad ur Rasulullah, who has been incarnated in the world again to spread Islam. We do not, therefore, need any new Kalimah. Albeit, a new Kalimah would have been necessary, if some other person had been reincarnated instead of Muhammad ur Rasul Allah. So contemplate!” (Kalimatul Fasl, page 158).
QADIANI BELIEF: PROPHETHOOD OF MUHAMMAD STANDS ABROGATED AND HIS KALIMAH STANDS CANCELLED
A little thought on the above-cited passages makes it quite clear that not only do the Qadianis consider Mirza Ghulam Ahmad to be a Prophet and Messenger (of Allah) but they also consider Mirza of Qadian a complete incarnation of Muhammad (SAW) and as such recite his (Mirza’s) Kalimah. They consider as Kafirs all those who recite the Kalimah of Muhammad of Arabia (SAW). This proves that for the Qadianis the Kalimah of Muhammad of Arabia (SAW) stands cancelled.
If we look more closely into the issue we shall find that according to the Qadiani belief-like that of the Bahais - the period of the Prophethood and Apostleship of Muhammad of Arabia (SAW) has expired and it stands repealed for all practical purposes, because according to the Qadiani belief the basis of salvation lies in obeying the Qadiani Mirza only. So Mirza said:
“Say to them: if you love God then come and obey me so that God also may love you”.
(Mirza Qadiani’s "revelation as cited in Haqiqatul Wahi, Page 79/82, Lahore, 1952; Roohani Khazain. Vol. 22, p. 82. Also see pages 46, 62, 81, 182, 205, 277, 360, 363, 378, 395, 495, 630, 634, in Tazkirah, 2nd Edition).
"In Braheen-e-Ahmadia, God has called me by the name of Ibrahim, as He said: “This means: Salutation on Ibrahim (i.e. this humble man [Mirza]). We truly made friends with him and saved him from every sorrow. And O ye who follow, let the place of Ibrahim’s footsteps be the place of your prayers. That is, obey completely so that you may attain salvation.” (Arbaeen, Vol. 3, pp. 30-31; Roohani Khazain, Vol. 17, p. 420).
“As regards the assertion (verse from Quran regarding Ibraham) this is a verse of the holy Quran. Here it means: Perform your prayers and hold beliefs on the pattern of Ibrahim (i.e. Mirza Qadiani) who has been sent, and mould yourself on his model in every matter”. (Arbaeen, Vol. 3, p. 31; Roohani Khazain, Vol. 17, p.42).
“Similar is the verse (same verse quoted above) which contains a hint that at a time when the Ummat-e-Muhammadia will become divided into many sects, then during the last era an Ibrahim (i.e. Mirza Qadiani) will be born and out of all the sects, the sect which follows this Ibrahim, (i.e. Mirza!), will be saved”. (Arbaeen, Vol. 3, page 32; Roohani Khazain, Vol. 17, p. 4213.
“My teachings contain orders as well as prohibitions and renovation of important injunctions of the Shari’at. For this reason God has named my teachings and the ‘wahi’ (revelation) that comes to me as a 'boat. Thus see, God has declared my ‘wahi’, my teachings and allegiance with me to be Noah’s Ark and the basis of salvation for all human beings. Let he who has eyes may see and he who has ears may hear.” (Arbaeen, Vol. 4, footnote of page 6; Roohani Khazain, Vol. 17, p. 435).
Thus obedience to Mirza Qadiani’s prophethood, teachings, ‘wahi’ and his renovated Shari’at is allegedly the only basis for salvation for all mankind. This only means, that the Shari’at of Muhammad of Arabia (SAW), his teachings and 'wahi" are no longer the basis of salvation. In other words, Mirza’s incarnation has rendered all these useless, suspended and abolished.
