´Asma bint Yazid narrated that the Prophet (ﷺ) said:` “Allah's greatest name is in these two Ayah: ‘And your deity is One deity, there is none who has the right to be worshipped but He, Ar-Raḥmān, Ar-Raḥīm.’ And the Opening of Al-`Imrān: ‘Alif. Lām. Mīm. Allah, None has the right to be worshipped but He, the Ever living, the Sustainer.’”

Explanation: 1: Your God is only one true God; there is no deity except Him; He is ar-Rahman (the Most Merciful), ar-Rahim (the Especially Merciful). (al-Baqarah: 163) (i.e., ar-Rahman, ar-Rahim)
2: Alif Lam Meem, Allah—there is no deity except Him, the Ever-Living (al-Hayy), the Sustainer of all (al-Qayyum). (Aal Imran: 1-2) (i.e., al-Hayy, al-Qayyum)
Note: (In the chain of narration, "Ubaydullah ibn Abi Ziyad al-Qaddah" and "Shahr ibn Hawshab" are weak, but this hadith is strengthened by the narration of Abu Umamah, thus it is hasan li-ghayrihi (good due to supporting evidence). See: al-Sahihah no. 746)
