What are the most important rights that Islam respects?

Islamic rights are numerous, and among the most important are: 1. The Right of Allah: This includes His Oneness in Essence, Names, Attributes, and Actions, worshipping Him alone by devoting all forms of worship to Him, and thanking Him for His blessings. 2. The Right of the Messenger: This entails loving him, obeying him, and sending blessings upon him, by obeying him in what he commanded, believing him in what he conveyed, avoiding what he forbade, and worshipping Allah according to what he legislated. 3. The Right of Parents: This includes obeying them, respecting them, showing humility towards them, being kind to them, spending on them, praying for them, maintaining ties with their relatives, and honoring their friends, with an emphasis on the greatness of the mother's right. 4. The Right of a Muslim upon a Muslim: This involves loving him, advising him, relieving his distress, concealing his faults, supporting him in truth, respecting his neighborly rights, honoring his guest, returning greetings, visiting the sick, accepting invitations, saying "Yarhamuk Allah" to one who sneezes, and following funerals. 5. The Right of the Neighbor: This includes initiating greetings with him, visiting him when sick, offering condolences, congratulating him, forgiving his mistakes, concealing his private matters, enduring his harm patiently, giving him gifts, lending to him, lowering one's gaze from his forbidden intimacies, and guiding him to what benefits him. Harming a neighbor is forbidden.

Islam also ordained rights for the ruler over the ruled and for the ruled over the ruler, as well as rights between spouses, and other just rights.
