Is what was mentioned on the website "Ahmadiyya Qadiani Network in the Balance" about the Ahmadiyya sect correct, and are the Ahmadiyya the Qadianis, or do they differ from them?

We have not reviewed the aforementioned website, and it is not within our purview to pass judgment on websites. The misguidance of the Ahmadiyya Qadiani has been previously clarified. There is another sect of Muslims called the Ahmadiyya who attribute themselves to Sheikh Ahmed Al-Rifa'i; they are originally Muslims, but they have many innovations (bid'ahs) and deviations, and they are different from the Qadiani. Sheikh Ahmed Al-Rifa'i loved the Sunnah and was known for his uprightness, and the deviation occurred among those who attributed themselves to him.
