Many scholars and Muftis say that saying "Ya Ali madad" is not permitted even it was for seeking intercession…

Answer

In the name of Allah: There is no doubt that resorting to other than Allah is not considered polytheism if it was within the permissible limits. My son, don’t you resort to your hand to take a thing, don’t you resort to clothes to protect yourself from cold, and don’t you hear the channels all over the Islamic countries broadcast after Athan "May Allah accept the intercession of the prophet (PBUH and elevate his position in heaven? Didn’t Allah order the Messenger (PBUH&HF) to resort to Ali (PBUH) for assisting him to break down Khaiber gate, where they failed to do so? Then, what is the meaning of polytheism, son? Polytheism is to worship other than Allah and to put a god with Allah (SWT). When you resort to a friend for doing something, you do not make a partner with Allah (SWT). There are supplications narrated about Imams' (PBUH) pilgrimages in which they ordered us to seek intercession from them (PBUH). These are narrated in the books of supplications and pilgrimage texts. Allah is the All Guide.
