The last book out of five books that I have been reviewing for the blessed month of Ramadhaan is the excellent:
صِفَةُ صَوْمِ النَّبِيِّ صلى الله عليه و سلم فِي رَمَضَان
Sifatu-Sawm-in-Nabiyee Sallallahu ‘alayhi wa salam fee Ramadhaan
The Description of the Fast of the Prophet, peace be upon him, in the month of Ramadhaan

Written by both Shaykh ‘Alee Hasan al-Halabee & Shaykh Saleem bin ‘Eeed al-Hilaalee (hafithahumaa Allah). This edition was printed by Daar Ibn Hazam by the Maktabah Islaamiyyah. It is 138 pages and contains 24 sections on how the Prophet, peace be upon him observed his fast. Some sections include but not limited to; the Benefits of Fasting, the Benefit of the month of Ramadhaan, the Obligation to fast in Ramadhaan, a section on Suhoor, the Iftaar, those things that nullify the Fast, making up the days of fast that are missed, Laylat-ul-Qadr, I’tikaaf, Taraweeh, Zakaat-ul-Fitr and weak narrations that have been spread concerning Ramadhaan.
