Meanwhile, in the Qur’an Balaghah idioms are detailly characteristics with high vocabulary enrichment, even Uslub Ilmi or Uslub Adabi. Thus, researchers employe to conduct research <em>Tahlilu-l-Asalib Al-Balaghiyyah Fi Surati-l-Fath</em> as an object that has many idioms describing <em>maghfiroh of Allah</em>, Muslimin Independence on unbelievers, socialization, attitude, ibadah, and advice. Understanding Alqur’an with the Arabic Language needs comprehensive learning, and understanding the Arabic Language itself needs three bits of knowledge; <em>Nahwu, Sharaf</em>, and <em>Balaghah</em>. The researchers limit  <em>Balaghah</em> as a focused matter; it delineates idioms. Qur'an consists of many idioms that must be understood well by a Muslim who expects to master Alqur’an. Based on the aforementioned last point, the researchers apply a qualitative method to reach the goals. The data is collected by books and documentation to investigate the finding. The result of the finding many Uslub in there, they are <em>Al-Isti’arah Almakniyah, Isti’arah Tashrihiyah, Tasybih Tamtsili, Kinayah, Iltifat, Ithnab, Shiyagul Mubalaghah, Iijazul Qashri, Thibaqu Iijabi, Thibaqu Sulbi, Saja’ dan Muqabalah.</em> For the meaning in it, they are <em>Al-Mubaya’ah, Al-mubadalah, Ad-diin, Atta’dziim, Aliltifat, Attakriir, Almubalaghah, Attasyriif, Attarghiib, Attadhad, Attashdiiq dan Almuqabalah</em>.
