It is narrated from Muhammad that he says: Hazrat Abu Musa (may Allah be pleased with him) wrote a letter to Amir from Abdullah bin Qais to Amir bin Abdullah ... who was previously called Abd Qais ... To proceed! I had made a covenant with you on a matter and it has reached me that you have changed. Therefore, if you are still upon the agreement I made, then fear God and remain steadfast. And if you have changed, then fear God and return.
