It is a big Shirk to make 'SAJDA" before the Mazar of a dead saint and ask for help. Even the Saudis don't allow us to bow and ask for any help from the noble Mazar of our Prophet as he is not alive. All this exploitation and deviation take place because we lack Quranic knowledge due to simply reading, reciting and memorizing/Hifz of Quran without understanding to please our Mullajees instead of Allah. There is no 'Hukum'/order of Allah to learn Arabic language to read and understand the Holy Quran or otherwise to simply read and do Hifz/memorization of Quran without understanding.
Allah is above languages and dialects etc. and the Arabic Quran was bestowed basically for the then deviated and erring Arabs to warn and guide them to HIS Right Path. Please read: 12:2/19:97/41:2,44/42:7/43:3. Allah's previous three Holy Books were bestowed not in Arabic but in the languages of the time to warn and guide the then erring and deviated humanity to HIS Right Path.
The Christians remained backward so long as they remained under their priests' religious control who did not allow them to read the translation of BIble and faced 'inquisition'/severe punishments at the hands of their Pope, Cardinals, Bishops. But once they shook off the priests' control and started reading of translation of Bible to understand and follow Christianity, they progressed much in all sphere of life including education and knowledge, science and technology leaving us far behind and backward in all spheres.
That is why Allah has strictly prohibited priesthood in the Holy Quran (9:31,34/57:27). Allah directs us to follow only those who are on the Right Path of Allah as per Quran and never ask for any payment (36:21) as this is a Fi Sabil Illah voluntary work.
Unless our sincere Ulemas/Muftis/Masajid Imams project and promote Quranic Mohukamath/specific Guidance (3:7) on all matters of life, we will continue to remain religiously backward to indulge in such Shirk and Bidah, un Islamic customs and practices, falsehood, lies, sins and evils, over-belief in weak and unauthentic Hadiths, tales and stories, sayings and traditions etc. not according to Holy Quran.
Our Muftis are cordially requested in the name of Allah to be bold enough to issue FATWAS in this regard and also ask our ignorant Ajami Muslims to read Quranic translation again and again to understand Islam correctly free from all exploitation and deviation and to follow all the Mohukamath of Allah in letter and spirit to achieve the Blessings of Allah.
