3:2Aal-i-Imraan

“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.’”

"Allah's Greatest Names is in these two verses: "And your Ilaah (God) is One Ilaah (God), none has the right to be worshipped but He, the Ever-Merciful, the Mercy-Giving' and the beginning of Surah Al 'Imran, "A.L.M Allah, there is no deity but He, the Living, the Eternal."

The Prophet (ﷺ) came to them in the swelling place of immigrants and a man asked him: Which is the greatest verse of the Qur'an ? The Prophet (ﷺ) replied: Allah, there is no god but He - the Living, the Self-Subsisting Eternal. No slumber can seize Him nor sleep."

"The final words of the Adhan are: 'Allahu Akbar, Allahu Akbar; La ilaha illallah (Allah is the Greatest, Allah is the Greatest, there is none worthy of worship except Allah.)'"

"La ilaha illallah, Wahdahu la sharika lah, lahul-mulku wa lahul-hamdu, yuhyi wa yumitu, wa huwaala kulli shayin qadir (There is none worthy of worship except Allah alone with no partner or associate, His is the dominion and to Him be praise, He gives life and death, and He has power over all things)." Then he walked until he reached level ground, then he hastened until the ground began to rise. Then he walked until he came to Al-Marwah, and he did the same there as he had at As-Safa, until he had finished his Sai."
