as-salamu `alaykum How many years elder was Amir al-Hamza radi Allahu `anh than the beloved Messenger sal Allahu `alayhi wa sallam? I have read in a book that Ibn Sayyid al-Nas wrote that Amir al-Hamza radi Allahu `anh was two years elder, whereas Hafidh Ibn Hajar said between two to four years. Any clue?
