The best way to my knowledge is Khalil, prosody and rhyme

Among the eminent sciences of Arabic are two: Al-‘Arud (prosody) and Al-Qafiyah (rhyme), which deal with Arabic poetry by regulating its meter and verifying its rhyme by affirming what the Arabs have established for them and denying what they have rejected. These two sciences are of great importance and high status due to the precision of their issues and the numerous similarities within them. I have studied both sciences as a student and teacher, and I found them difficult to master because people tend to neglect them despite their great value and the desire to learn them. I have often spoken about this difficulty and avoidance, and Allah guided me with His good success to these reasons: - In many books on Al-‘Arud, references are made to the unknown, and among these references is that before starting to mention the meters, they introduce a chapter titled: "The Titles of the Verses," in which they mention the complete, hemistich, broken, and exhausted types. They define the complete as: what fulfills all its parts, and the hemistich as: what has its ‘Arud (meter) and its ‘Ud (foot) omitted. You see them referring to the unknown by mentioning the ‘Arud and the ‘Ud before the beginner knows what the ‘Arud and the ‘Ud are?! - In both old and modern writings on these two sciences, the authors have limited themselves to the verses cited by Al-Khalil and his companions, not going beyond them, many of which are not clear. This ignorance of their meaning prevents familiarity and mastery of them. Moreover, their repetition across different books makes reviewing them less beneficial. When their evidence differs and their forms vary, it is more likely to make them firmly rooted in the mind. - The sciences preceded and were subjected to modern educational principles, so that each chapter of grammar, for example, was followed by an application to its issues, testing the mind and demonstrating the level of mastery, clarifying ambiguities, and establishing distinctions. Al-‘Arud and Al-Qafiyah were the first sciences to be subjected to this approach, but we find in them only listing issues, unifying examples, and reducing their number, without following the progressive method evident in other sciences. Therefore, I have authored this work, avoiding those flaws.
