In his book (تحفة القريب والمجيب) Shaykh Muqbil bin Haadee (rahimahullaah) in answer to question no. 75, stated about Shaykh Rabee bin Haadee, when asked about which Scholars to refer back to:
والشيخ ربيع بن هادي المدخلي، فهو آية من آيات الله في معرفة الحزبيين، لكن لا كآيات إيران الدجالين
And Shaykh Rabee bin Haadee al-Madkhaliee, for he is a sign amongst the signs (aayaat) of Allaah in knowledge of the Hizbiyyeen, but not like the aayaat of Iraan, the Dajjaaleen.
Source: From the Shaykh's book as indicated and compiled in (الثناء البديع من العلماء على الشيخ ربيع) by Shaykh Khalid al-Dhufayree. Some of the Hajaawirah have attempted to justify Ghuluww in Yahya al-Hajuri (made by the ignorant students of Yahya al-Hajuri and his poets) by claiming that Ahl al-Sunnah also make Ghuluww in Shaykh Rabee, but the difference is that these commendations are coming from genuine, deeply-rooted Scholars who are in a position to know the true worth of a Scholar, such as Shaykh Ibn Baz, Shaykh al-Albani, Shaykh Ibn al-Uthaymeen, Shaykh Muqbil and others.
And in his introduction to the book of Shaykh Muhammad al-Imaam, "Tanweer al-Dhulumaat", Shaykh Muqbil says (p. 6):
فكم من حزبي كانت له صولة وجولة، بل تطلق عليه الألقاب الضخمة، وبعد بيان أهل السنّة حاله، مات وماتت فكرته. ومن علماء أهل السنّة الأفاضل المعاصرين الواقفين في وجه أصحاب الباطل: الشيخ محمد ناصر الدين الألباني رحمه الله، والشيخ عبدالعزيز بن باز رحمه الله، والشيخ ربيع بن هادي، وآخرون
And how many a Hizbee (has there been) who had some sway (power, strength, stronghold), rather exaggerated titles would be applied to him, yet after Ahl al-Sunnah clarified his condition he died and his ideology died with him. And from the esteemed contemporary Scholars of Ahl al-Sunnah who stand in the face of the people of falsehood are Shaykh Muhammad Nasir al-Din al-Albani (rahimahullaah) and Shaykh Abd al-Azeez bin Baz (rahimahullaah) and Shaykh Rabee bin Haadee and others.
