REVEALED, in the consensus of most of the authorities, in the year 9 H., this surah deals predominantly with social ethics. Beginning with the reverence due to the Prophet and - by implication - to the righteous leaders of the community after him, the discourse culminates in the principle of the brotherhood of all believers (verse 10) and, in its widest sense, the brotherhood of all mankind (verse 13). The concludingpassage (verses 14 ff.) points out the difference between true faith and a mere outward observance of religious formalities. The title is derived from the mention of the word al-hujurat in verse 4.
