A book on Hadith Principles

This monograph on ĥadīth principles by Imām Sayyid-Sharīf is an
excellent introduction to hadith sciences and nomenclature for students
and non-specialists alike. This started off as an appendix to the
translation of Imām Nawawī’s Arbaýīn. However, a plain translation of a
breviloquent epistle would be daunting to the non-specialist, and perhaps
fail spectacularly in its stated purpose of enlightening the beginner.
Hence, explanatory footnotes were indispensible, and kept piling up until
eventually, what was expected to be an ‘appendix’ reached the size of the
main work (i.e. Arbaýīn). After consultation with reviewers, it was
decided to release this as a separate work.
Many thanks to brothers, especially úlamā, who assisted in proofreading
and in reviewing this work. Any mistakes that still remain are owing to
my own shortcomings and gaps in knowledge. We ask Allāh táālā to
forgive us for our lapses.
