Does Islam represent a responsibility for every Muslim man and woman, like a contract that entails rights, duties, rewards, and punishments? What is the meaning of this responsibility and its requirements, and what is the ruling on one who neglects it?

The term "responsibility" is modern and expresses a person's commitment to duties for which they will be questioned and held accountable. In Islam, responsibility means a person's fulfillment of what Allah has obligated upon them, and they are held accountable for their failure to do so, as in the verses: "And I did not create the jinn and mankind except to worship Me" (Quran 51:56), "Then We will surely question those to whom [messengers] were sent, and We will surely question the messengers" (Quran 7:6), and "And you will surely be questioned about what you used to do" (Quran 16:93). This responsibility is divided into two types:

1. Individual Obligations ( تكاليف عينية): These are incumbent upon each individual person, and they will be questioned about them before Allah, such as faith, prayer, fasting, honoring parents, and caring for one's family (as in: "O you who have believed, protect yourselves and your families from a Fire" (Quran 66:6)), and every guardian is responsible for his flock.

2. Collective Obligations (تكاليف كفائية): These are incumbent upon the entire community, and if some Muslims perform them, the sin falls away from the rest, such as the funeral prayer, learning religious sciences, enjoining good and forbidding evil, and helping those in need. The Lawgiver, in these cases, looks at the act itself, not at the specific doer.
