All perfect praise be to Allah the Lord of the Worlds. May His peace and blessings be upon our Prophet Mohammad and upon all his family and companions.

The name of Majesty "Allah" is the proper name for the Sublime Essence, the Necessarily Existent, deserving of all praise. Among its characteristics, according to the preponderant view of the scholars, is that it is the Greatest Name of Allah (Ismullah al-A'ẓam). Imam Al-Khatib Al-Shirbini Al-Shafi'i, may Allah have mercy on him, said: "According to the verified scholars, it [i.e., the name of Majesty 'Allah'] is the Greatest Name of Allah, and it has been mentioned in the Noble Qur'an in two thousand, three hundred and sixty places." [Al-Iqna', Vol.1/P.6]. Imam Ibn Abidin Al-Hanafi, may Allah have mercy on him, said: "Hisham reported from Muhammad from Abu Hanifah that it [i.e., the name of Majesty] is the Greatest Name of Allah, and this was the view of Al-Tahawi and many scholars." [Radd Al-Muhtar, Vol.1/P.7].

The fundamental principle is that the name of Majesty "Allah" should be uttered completely in acts of worship, i.e., with all its letters including the letter 'Hā'. The jurists of the Shafi'i school have stipulated that no letter may be omitted from the letters of the Takbirat al-Ihram (the opening 'Allahu Akbar' of prayer), including the name of Majesty, for the prayer to be valid. Imam Al-Malibari Al-Shafi'i, may Allah have mercy on him, said: "For one who is capable, the specific wording 'Allahu Akbar' is obligatory due to following the precedent (Itba'), or 'Allahu al-Akbar'. 'Akbar Allah' does not suffice, nor does 'Allahu Kabir' or 'A'ẓam', nor does 'Al-Rahman Akbar'. Omitting a letter from 'Allahu Akbar' is detrimental [to its validity], as is adding a letter that changes the meaning, such as prolonging the hamza in 'Allah', adding an alif after the ba', adding a waw before the name of Majesty, inserting a moving or stationary waw between the two words, and likewise prolonging the alif between the lam and the ha' to an extent that no reciter would consider." [Fath al-Mu'in, p. 94].

The jurists of the Hanafi school concurred with this. Imam Al-Sharnabalali Al-Hanafi, may Allah have mercy on him, stated while discussing the conditions for the validity of Takbirat al-Ihram: "That one does not omit the 'Hā' from the name of Majesty." [Maraqi al-Falah, p. 85]. Imam Al-Tahtawi Al-Hanafi, may Allah have mercy on him, said: "If an oath-taker, a slaughterer, or one saying the opening Takbir for prayer omits the 'Hā' from the name of Majesty, there is a difference of opinion regarding the validity of his oath, the permissibility of his slaughtered animal, and the validity of his Takbirat al-Tahrimah. Therefore, one should not neglect this out of precaution." [Hashiyat Al-Tahtawi 'ala Maraqui al-Falah, p. 224].

The utterance "Alla" (اللا) is not considered indicative of any name of Allah the Exalted or any of His attributes. Imam Al-Shabramallisi Al-Shafi'i, may Allah have mercy on him, said: "It also remains [to be considered]: if one omits the 'Hā' from the name of Majesty and says 'Alla', is this considered an oath or not? There is consideration [on this matter], and the more correct view is the latter [that it is not]; because without the 'Hā', it is not one of His names nor His attributes." [Hashiyat Al-Shabramallisi 'ala Nihayat al-Muhtaj, Vol.8/P.178].

Furthermore, if the name of Majesty is uttered with the omission of the 'Hā' with the intention of belittlement or distortion, this constitutes disbelief (Kufr), due to its transgression against the sanctity of Allah's name. However, if it is uttered without such intent, such as if this pronunciation is prevalent in the dialect of a tribe or region, or commonly used by the general populace without that intention, then the ruling is more lenient, provided that the person who does so is advised and taught the correct pronunciation of the Name.

In conclusion, the utterance "Alla" (اللا) is not considered a name of Allah, the Blessed and Exalted, nor an attribute of His. One must be mindful of this when performing verbal acts of worship, such as the Takbirat al-Ihram, the Adhan (call to prayer), and the Tasmiyah (saying 'Bismillah') when slaughtering an animal. The matter is treated strictly here, as some scholars have explicitly stated the invalidity of the act of worship if the 'Hā' of the name of Majesty is omitted. The general populace should be advised and taught the correct pronunciation of the Name. And Allah the Exalted knows best.
