What Are Allah’s Rights over His Slaves?

The Prophet (sallaaAllahu alayhi as sallam) said:
Allah’s right over his slaves is that they worship him alone and not to ascribe any partners to him”
Collected by: Al-Bukhaari #2856 & Muslim #30
Note: Do not give any of Allah’s rights to anyone or anything besides him, doing so will go against the purpose of our creation and lead a person to the worst and biggest sin.
