  Mohammad Ali Foroughi is considered one of the famous contemporary men in politics, culture and law. His two political and cultural aspects have caused him to correspond with many educated friends about these issues. Due to Foroughi's familiarity with ancient literature and attachment to Iranian culture, his letters have been influenced by the structures of his predecessors in addition to ancient literary works. Looking at these correspondences, one can see the influence of Farahani's letters in them. It is worth mentioning that while imitating the style of Ghaem Magham, he had innovations in his letters. This issue, article aims to reveal the extent of Foroughi's innovation and influence on Ghaem Magham`s letters by considering Ghaem Magham`s letters as an example of the return style. For this purpose, in this research, 11 letters from Foroughi's letters, collected in the Zoka-ul-Mulk's policy book, and 11 letters from Ghaem Magham institutions, which were written in three fields of friendship, politics and social; Have been analysed. By examining these letters, it was found that although Foroughi was influenced by the letter structure, literary techniques, and linguistic features of Farahani's letters, he made innovations in the field of content and concepts. Zakaul-Molk's innovations can be seen in combining the retro style with modern socio-political concepts. In writing letters, Foroughi paid special attention to the needs of the times and people's understanding. Therefore, besides being influenced by the return style, he has overcome its weaknesses with some expressive tricks and subtleties. By using this way of writing, Foroughi has achieved the two goals of attracting the audience's attention in the direction of promoting Persian culture and literature and conveying modern concepts along with reports on current issues of the society. In his political and social letters, we see imitation of difficult literary-historical texts; However, his friendly correspondences are very tender and heartwarming due to the imitation of lyrical texts. So reading these letters gives the reader more literary pleasure than social letters.
