There are many books of Elm al-Rijaal mentioning the good companions who remained faithful to the Prophet (SAWA) and Ahlul Bayt (AS). Allama Sharafuddin of Lebanon mentioned names of 160 companions from them in his book : Jarallah questions answers, page 14 to 25.
Sayyed Hasan al-Sadr of Kadhimiyyah, author of Nihayat al-Dirayah, mentioned names of hundreds of faithful companions.
These books and most of Elm al-Rijaal books are in Arabic.
Most of the companions who passed away during the life of the Prophet (SAWA) or been martyred in the battles of that period are praised. Those who remained faithful after the Prophet are also praised.
