Abu Musa Ashari reported,

The Prophet ﷺ said, "There are three who will be given their reward twice. A man who had a slave-girl whom he disciplined and disciplined her well, taught her and taught her well, then freed her and married her. A slave who fulfilled the right of his Lord and the right of his masters. And a man who believed in his own scripture and also believed in Muhammad ﷺ."The narrator said, Shaybi said to me, "Take this hadith for nothing. Even if you had traveled all the way to Kirman to obtain it, that would have been a small price."

حدثنا محمد بن جعفر حدثنا شعبة عن صالح عن الشعبي عن أبي بردة

عن أبي موسى

عن النبي ﷺ قال ثلاثة يؤتون أجورهم مرتين رجل كانت له أمة فأدبها فأحسن تأديبها وعلمها فأحسن تعليمها ثم أعتقها فتزوجها ومملوك أعطى حق ربه عز وجل وحق مواليه ورجل آمن بكتابه وبمحمد ﷺ قال قال لي الشعبي خذها بغير شيء ولو سرت فيها إلى كرمان لكان ذلك يسيرا
