Musnad Ishaq

Benefits:
➊ The Messenger of Allah sallallahu alayhi wa sallam was sent as a mercy to the worlds. As Allah the Exalted says:
﴿وَ مَآ اَرْسَلْنٰكَ اِلَّا رَحْمَةً لِّلْعٰلَمِیْنَ﴾ ( Al-Anbiya: 107)
People caused him harm, yet despite this, the Messenger of Allah sallallahu alayhi wa sallam forgave them and supplicated for his ummah. When people pelted him with stones in the town of Ta’if, he prayed for their guidance. Similarly, during the Battle of Uhud, when his blessed tooth was martyred, he supplicated:
((اللهم اغفر لقومي فإنهم لا يعلمون)) (Muslim: 4646) “O Allah! Forgive my people, for indeed they do not know.”
The Messenger of Allah sallallahu alayhi wa sallam stated the above after the Battle of Uhud, when he killed Ubayy ibn Khalaf. Ubayy ibn Khalaf had said: “I will kill Muhammad sallallahu alayhi wa sallam (astaghfirullah).” During the Battle of Uhud, the Messenger of Allah sallallahu alayhi wa sallam struck him with a spear, causing him a minor scratch, and he said to the Quraysh of Makkah: “Muhammad sallallahu alayhi wa sallam has killed me.” The people said: “By Allah! You have lost heart, otherwise you have no serious injury.” He replied: “Muhammad sallallahu alayhi wa sallam had told me in Makkah that he would kill me, so by Allah! If he had spat on me, my soul would have departed.” Eventually, this enemy of Allah died at the place of Sarif while returning to Makkah. ( Sirah Ibn Hisham: 2/84)

➋ ... It is understood that the title “Shahanshah” (King of Kings) is extremely disliked for the creation, because this title is befitting only for Allah, the Possessor of Majesty. Its meaning is “the King of kings,” and adopting such a name resembles the name of Allah, which is in direct opposition to the Qur’anic text: ﴿لَيْسَ كَمِثْلِهِ شَيْءٌ﴾ (). Therefore, this name is only befitting for Allah the Exalted and should be reserved for Him alone. ( Bahjat al-Nufus: 4/185)
It is stated in “Fath al-Bari” that, like “Shahanshah,” there are other names which are specific to the Essence of the True One, Glorified and Exalted is He, and it is forbidden to name anyone else with these names. These include: (1) Khaliq al-Khalq (Creator of Creation), (2) Ahkam al-Hakimeen (Most Just of Judges), (3) Sultan al-Salateen (Sultan of Sultans), and Amir al-Umara (Commander of Commanders). According to Hafiz Ibn Hajar rahimahullah, “Rahman,” “Quddus,” “Jabbar,” and others are also included in this.

Allamah ‘Ayni, Abu Muhammad ibn Abi Jamrah, and Allamah Zamakhshari’s opinion is: Names such as Qadi al-Qudat (Judge of Judges), Kabir al-Qada (Greatest of Judges), and Aqda al-Aqda (Most Judicious of Judges) should also not be used. However, the explicit use of names like Aqda and Qadi al-Qudat is found in the statement of the Messenger of Allah sallallahu alayhi wa sallam. As he said regarding Sayyiduna Ali radi Allahu anhu ibn Abi Talib: “Aqdaakum Aliyyun” (“The most judicious among you is Ali”). However, it should be clear that when someone is given the title Qadi al-Qudat or Aqda al-Qudat, the intent should be that the person is the most just, most knowledgeable, or the best judge among the people of his time, country, or city.
