To proceed: This is a concise treatise on uṣūl al-fiqh (the principles of jurisprudence)—its wording is simple, its meanings are clear, and it assists every reflective reader in learning the legal rulings. We ask Allah to make it beneficial to both its compiler and its reader; indeed, He is Most Generous and Bountiful.
