Sh. Ibn ʿUthaymīn (d. 1421), may Allāh have mercy upon him, was asked whether it was better to memorise a study-text (matn) of jurisprudence (fiqh) or a concise study-text of ḥadīth. The Shaykh responded:

“It is better to memorise a concise study-text of ḥadīth such as ʿUmdat al-Aḥkām and Bulūgh al-Marām, but he should not leave off consulting the speech of the people of knowledge and jurisprudence.”

Majmūʿ Fatāwá wa Rasāʾil al-Shaykh Muḥammad b. Ṣāliḥ al-ʿUthaymīn, vol. 26, p. 185.

Note: Both of the books mentioned by the Shaykh are books dedicated to including aḥādīth of the Prophet ﷺ pertaining to juridical matters such as purification, prayer, zakāh, fasting, ḥajj, buying and selling, marriage, jihād, capital punishments etc.

ʿUmdat-ul-Aḥkām by al-Ḥāfiẓ ʿAbd al-Ghanī al-Maqdisī (d. 600) contains aḥādīth reported by both al-Bukhārī and Muslim only (“agreed upon”). According to the al-Arnāʾūṭ edition there are 430 such aḥādīth. The best commentary is that of Ibn Daqīq al-ʿĪd (d. 702) entitled Iḥkām al-Aḥkām which a beginner may find difficult to grasp. Bulūgh al-Marām of Ibn Ḥajar (d. 852) is at least three times as large and contains 1582 aḥādīth according to al-Zuhayrī’s edition. The Shaykh has his own explanation of Bulūgh al-Marām in 15 volumes entitled Fatḥ Dhī al-Jalāl wa al-Ikrām bi Sharḥ Bulūgh al-Marām.
