Some verses of the Quran are similar in form. According to a group of Quran scholars, these instances are considered "repetitions," while others view them as "refrains." The noble verse "فَبِأَیِّ آلاءِ رَبِّکُما تُکَذِّبانِ" (So which of the favors of your Lord would you deny?) appears thirty-one times in Surah Ar-Rahman and is one of the most significant examples of similar verses. This research, conducted using a descriptive-analytical method and library resources, examines the literary, lexical, and interpretative dimensions of this topic. Based on the findings of this study, the refrain perspective is supported by stronger evidence. Additionally, the mentioned expression is not repetitive, and the term "آلاء" (favors) in these thirty-one verses does not carry the same meaning. The findings also clarify the notion of the blessings of the punishments in the hereafter, considering the principle of justice and the distinction between the ranks of the close ones and the righteous from the perspective of the refrain. Another finding of this research is that to better understand the message of the divine verses in the Holy Quran, it is necessary to refer to literary techniques in both Arabic and Persian. By studying the relationship between Arabic literature and Persian literature, one can access the deeper meanings of God's words, and this important aspect should not be overlooked in the interpretation of the Quran. The growth and perfection of literary techniques in the Persian language have been achieved by relying on the eloquent literature of the Arabic language.
