Tahrir al-Wasilah

Tahrir al-Wasilah (Arabic: تحرير الوسيلة; Clarification of the Means of Salvation; in Persian: تحریر الوسیله Tahrir al-Vasileh) is a book by Ayatollah Khomeini written as a commentary.

The book was part of the centuries-old tradition of commentaries on Islamic jurisprudence (fiqh) commonly written by leading Shia clerics working toward the status of Marja, for the use of their students and fellow clerics. The "Means" or "Intercession" this book was commenting on was Wasileh un-Nejat, (The Means of Salvation), by S. Abul-Hasan Isfahani. Khomeini's commentary covered socio-political issues such as jihad and "ordering the good and forbidding the evil", that had been abandoned by his contemporaries.

Written during Khomeini's exile, the book was started in 1964 in Turkey and finished in Iraq and comes in two volumes and four editions. The book has been called "substantial" and responsible for securing Khomeini's "reputation in the early 1960s", and raising his "status as a jurist". The book later became the subject of commentaries itself.
