The Sabbath was only prescribed, in other words, its consecration was made obligatory [only], for those who differed concerning it, with their prophet — these were the Jews. They were commanded to devote themselves solely to worship on Friday, but they said, ‘We do not want it’, and chose Saturday; consequently thereon [the observance of] it was enforced strictly on them; and lo! your Lord will judge between them on the Day of Resurrection, concerning that wherein they used to differ, with regard this matter [of the Sabbath], by rewarding the obedient and chastising the one who disobeyed by [his] violating its sanctity.
