( … ) “Qāʿidah Jalīlah fī al-Tawassul wa-l-Wasīlah” (A Sublime Principle on Intercession and the Legitimate Means), by Shaykh al-Islām; hadith verification (printed).

Shaykh Zuhayr al-Shāwīsh—may Allah preserve him—mentioned it in the introduction to Ṣaḥīḥ al-Jāmiʿ (1/51), ḥadith no. 1, citing the exact page. However, I have not come across anyone who actually ascribes the verification to the Shaykh, and Allah knows best.

I later examined the Islamic Office edition of the work and found no reference to Shaykh Nāṣir whatsoever. All it states is that Professors Shuʿayb al-Arnāʾūṭ and Aḥmad al-Qaṭifānī checked the text against the Ẓāhiriyyah manuscript.

The hadith-related annotations in the book are fewer than the fingers of one hand, extremely brief, and make no mention of al-Albānī; Allah knows best.

“Qāmūs al-Bidʿ” (Dictionary of Innovations), authored. He arranged it by topical chapters, did not complete it, and it is now lost.

“Qāmūs al-Ṣināʿāt al-Shāmiyyah” (Dictionary of Damascene Crafts) by Muḥammad Saʿīd al-Qāsimī; hadith verification in collaboration with the scholar Muḥammad Bahjat al-Bayṭār (printed).

The author, al-Qāsimī, passed away before finishing the work, so his son, the scholar Jamāl al-Dīn al-Qāsimī (d. 1332 AH), completed it in cooperation with Ustādh Khalīl al-Aʿẓam (d. 1342 AH). Their effort was not limited to completion; they also supplemented it with additional material that met the author’s criteria.

It was later published by his grandson Ẓāfir al-Qāsimī in two volumes: the first contains the original text, while the second comprises the supplement together with the additions and scholarly indexes.

The book is a gem in its field, without precedent; its benefits become clear to anyone who studies it in full. It is easy to consult and attests to the broad learning of the Qāsimī family.

From what I have seen, the two shaykhs’ hadith verifications are not comprehensive for every report in the book, nor did they write a preface to explain their work; Allah knows best.

See 2/234–236, where there are narrations that have not been verified.

“Qiṣṣat al-Masīḥ al-Dajjāl wa-Nuzūl ʿĪsā (peace be upon him) wa-Qatluh Iyāh ʿalā Siyāq Riwayat Abī Umāmah (may Allah be pleased with him), with additional material authenticated from other Companions,” authored. It was left incomplete.

“Qiyām Ramaḍān: Faḍluhu, Kayfiyyat Adāʾihi, wa-Mashrūʿiyyat al-Jamāʿah fīh” (Standing in Prayer during Ramadan: Its Virtues, the Manner of Performing It, and the Legitimacy of Congregational Observance), authored (printed).
