Are the following books approved and reliable for issuing fatwas in the Maliki school of thought, and is it permissible to derive fatwas from them: Hashiyat al-Sawi on al-Sharh al-Saghir, Hashiyat al-Dusuqi on al-Sharh al-Kabir, Mukhtasar Khalil with its commentaries (Mawahib al-Jalil, Al-Taj wal-Iklil, Al-Iklil), and Sharh Matn al-Ashmawiyyah by al-Sharnubi?

The mentioned books (Mukhtasar Khalil and its commentaries and glosses, and Matn al-Ashmawiyyah and its commentaries) are among the most important relied-upon books of furu' (branches of Islamic law) in the Maliki madhhab (school of thought). Mukhtasar Khalil is a great book, small in size yet abundant in knowledge. It comprehensively gathered and contained, specializing in clarifying what constitutes the fatwa, the most preferred, and the strongest opinion. Its commentaries and glosses are subservient to it, explaining its wording, clarifying its meanings, and favoring one opinion over another where there is a difference of opinion. These books are well-known and relied upon by followers of the Maliki madhhab, and they are studied in many Islamic countries. From them, legal rulings and fatawa are derived. They are often characterized by their focus on the well-known opinion within the madhhab or the most preponderant one.
