Manners with Allah include establishing His worship and obedience, glorifying Him, the Mighty and Majestic.. A person should not put himself ahead of Allah by declaring lawful what is unlawful or declaring unlawful what is lawful, or by obligating something which Allah has not obligated – among other etiquettes and manners. Similarly, a person must not disobey Allah—whether in private or in public—because whoever disobeys Him has not shown proper manners with Allah, the Mighty and Majestic.
