“Islam appealed not only to nobles but to common people for its ideology of individual worth and equality” Explain? Someone please help me!!!

There is a relation in Islam between individual responsibility and the rights and privileges derived from membership in the community. Individual obligations must be met before one can claim a portion from the community of which he is part. Each member of a society must fulfill his own obligations and rely on others to fulfill theirs before that society can acquire the necessary reservoir of social rights and privileges which can then be shared by all. The notions of brotherhood and solidarity not only impose upon the community the duty to care for' its members, but also require each person to use his initiative to carry out individual and social responsibilities according to his ability.
