thanks for clarification. Do you know what 4 imams say about it..?
No broi. But to help with the concept consider the following Hadith:
Shahr bin Haushab reported:
I asked Umm Salamah (May Allah be pleased with her), "O Mother of the Believers! Which supplication did the Messenger of Allah (ﷺ) make frequently when he was in your house?" She said: "He (ﷺ) supplicated frequently: 'Ya muqallibal-qulubi, thabbit qalbi 'ala dinika (O Changer of the hearts make my heart steadfast in Your religion)."
[At- Tirmidhi]
The Messenger of Allaah (sallallaahu alayhi wa sallam) called upon Allaah. He used
Yaa Muqallibal quluub
Now have you ever heard any scholar say that al-muqallib [the Changer] is a Name of Allaah? No
Why? Because the word is annexed with hearts in the Hadiith. The Messenger of Allaah (sallallaahu alayhi wa sallam) used it in that way.
Is there any Verse of the Qur'aan or Hadiith which uses al-MuQallib? No.
Can we? No, because we keep ourselves to the Names of Allaah in the Qur'aan and Sunnah.
What about the whole phrase muQallibul quluub? Yes, you can say that is a Name of Allaah because the Messenger of Allaah (sallallaahu alayhi wa sallam) used it in that way.
That is why you have this
Fatwaa here which says:
فقد تقدم في الفتوى رقم: 96669، أن من العلماء من عد الأسماء المضافة مثل: ذو القوة، غافر الذنب، قابل التوب شديد العقاب، ذي الطول، رفيع الدرجات، من الأسماء الحسنى
[Paraphrase] We have mentioned in the Fatwaa 96669 that there have been scholars who considered Names in 'IDaafah like dhuu al-Quwwah, Ghaafir al-dhanb, Qaabil al-Taub shadiid al-'iQaab, rafii' al-darajaah etc. from among the Beautiful Names of Allaah.
وقال شيخ الاسلام في الفتاوى: ومن أسمائه التي ليست في هذه التسعة والتسعين اسمه: السبوح ـ وفي الحديث، عن النبي صلى الله عليه وسلم أنه كان يقول: سبوح قدوس ـ واسمه: الشافي ـ كما ثبت في الصحيح أنه كان يقول: أذهب البأس رب الناس، واشف أنت الشافي، لا شافي إلا أنت، شفاء لا يغادر سقما ـ وكذلك أسماؤه المضافة، مثل: أرحم الراحمين، وخير الغافرين، ورب العالمين، ومالك يوم الدين، وأحسن الخالقين، وجامع الناس ليوم لا ريب فيه، ومقلب القلوب، وغير ذلك مما ثبت في الكتاب والسنة.
Ibn Taymiyyah said: [Paraphrase] From among the Names of Allaah which are not in these 99 include
al-Subbuuh. It is mentioned in a Hadith that the Prophet (sallallaahu alayhi wa sallam) used to say: Subbuuh Qudduus
And His name al-Shaafii as is mentioned in an authentic Hadith which reads Remove the evil O Lord of mankind and give Shifaa, your are al-Shaafii there is no Shaafi except you, a Shifaa which leaves no disease
Likewise His Names which are in construct ['IDaafah] as
'arHamur raahimiin
rabb ul aalimiin
Maaliki yaw middiin
muQallibul quluub
[He continues on with the list]
On a closing note, it is always best to err on the side of caution when dealing with the Beautiful Names of Allaah. Imagine if you Name Allaah with a Name He did not Name Himself with? What will you do when you stand in front of Him on the Day of Judgement?
If you avoid a "Name" because you cannot find it in the Qur'aan and Sunnah and it turns out to be a Name on the Day of Judgement you will not be held accountable for naming Allaah with something which was not His Name.
Finally, it is imperative that one understand a matter prior to preaching it. One needs to research and understand the differences concerning the Names and the reasons for the differences before one begins to preach.
This is the Diin of Allaah. We must be very careful what we preach and say. This is a matter of the 'aakhirah.
