for those who don't know; Shaykh Monawwar Ateeq writes that this is:Imam Ahmad Riza Khan’s magnum opus work on the issue of combining prayers titled “Haajiz al-Bahrayn al-Waaqi an al-Jam bayn al-Salatayn”. The work combines Fiqh with Hadith and perfectly illustrates how a faqih analyses Hadith evidences. It will perhaps be the largest work on the topic when published.
Allah be praised! Shaykh Mufti Akhar Rida Khan[may Allah protect him] has completed the translation of Imam Ahmad Rida's superb book, Hajizu’l Bahrayn al-Waqi án Jamiyi’s Salatayn into Arabic. He was blessed with completing the translation of the great Imam's work in Al-Madina Al-Munawara during this week in the holy month of Ramadan. visit this link for more information on the book : http://www.razanw.org/modules/alahazratbooks/item.php?itemid=31&page=0
