Allah
This is the name that encompasses all meanings of His other names and attributes, and to it they all refer. No one but Him is worthy of worship.

The name “Allah” occurs 2724 times in the Qur’an. An example of this is what is mentioned in Sūrat Al-Fātihah, (All praise is due to Allah, the Lord of the worlds), in the Verse of Al-Kursi, (Allah - there is no god except Him, the Ever-Living, the Sustainer of all existence), and in Sūrat AlIkhlās, (Say, “He is Allah, the only One.) Some scholars said that it is the ever greatest name of Allah.

In light of this great name, I would say:
1. Know that you will attain happiness only through your belief in Allah, following His guidance, remembering Him a lot, showing gratitude to Him and worshiping Him properly.

2. Remember that Allah Almighty is the Most Beloved Being ever, and this is due to His perfection and beauty and the immense favors He bestows upon His creation. Hearts only enjoy tranquility through remembering Him and souls only enjoy pleasure by knowing Him. The Prophet (may Allah’s peace and blessings be upon him) said, “There are three qualities; whoever has them will taste the sweetness of faith: To love Allah and His Messenger more than anyone else…”1

3. Whoever knows Allah Almighty will possess such pride and tranquility that prompt him to fear none but Allah and to seek help only from Him.

4. The worst wrongdoing a person may engage in is to know that Allah is his Creator and nonetheless worship someone else, and that Allah is the One Who bestows favors upon him and nonetheless shows gratitude to someone else. The Prophet (may Allah’s peace and blessings be upon him) was asked, “Which sin is the greatest?” He said, “To set up an equal to Allah while He has created you.”2
