When a Name is muqayyad it means it has been used in combination with something. It is not stand alone. Without the combination it does not impart perfection in meaning. It does not impart praise. Take the word Mudhhib [ مُذهِب] You cannot add an alif laam to it, make it المذهب and claim it is the Name of Allaah. We have in a hadith: Narrated `Abdul `Aziz: Thabit and I went to Anas bin Malik. Thabit said, "O Abu Hamza! I am sick." On that Anas said, "Shall I treat you with the Ruqya of Allah's Messenger (ﷺ)?" Thabit said, "Yes," Anas recited, "O Allah! The Lord of the people, the Remover of trouble! (Please) cure (Heal) (this patient), for You are the Healer. None brings about healing but You; a healing that will leave behind no ailment." [Sahih al-Bukhaari Hadith No. 5742] Look at the phrase The Remover of trouble. mudhhib means Remover. Can you based on this Hadith add an Alif Laam to mudhhib and make it al-Mudhhib [the Remover] and say this Name belongs to Allaah? No, because the Qur'aan and Sunnah do not use it in that way. Instead, it is muqayyad with trouble. The Remover of trouble. This form is what imparts perfection in meaning. It imparts praise. مُذهِب البأس You use it like that in the muqayyad form because the Messenger of Allaah (sallallaahu alayhi wa sallam) used it like that. The same applies to muntaQim. Look at the Verses which use the word. Do they use it alone? Or do they use it in conjunction with the wrongdoers? Let me help you. Consider the following Verse And who is more unjust than one who is reminded of the verses of his Lord; then he turns away from them? Indeed We, from the criminals, will take retribution. [Qur'aan 32:22] Allaah takes retribution from the criminals. You have to use it like this. Does He take retribution from someone who is not a criminal? It is muqayyad. It is not stand alone like al-Rahmaan. It is not stand alone like al-Rahiim. It is not stand alone like al-Waduud. Has Allaah said anywhere in the Qur'aan that he is al-Muntaqim? No. He has used it in muqayyad form. Do you understand muqayyad now or are you still confused?
