Allah says: “Indeed, Allah commands justice, excellence, and giving to relatives, and forbids immorality, bad conduct, and oppression. He admonishes you that perhaps you will be reminded.”
(Surah An-Nahl 16:90)

The Prophet ﷺ said: “Whoever calls to guidance will have a reward similar to those who follow him, without that detracting from their reward in the slightest.”
(Sahih Muslim)
