 this was how almamun was during his time. the evidence for what we have said about him is what we have seen in his letter to ishaq ibn ibrahim regarding the jurists and hadith scholars while he was in the levant. in it he reported one fault one by one and about his condition and affairs most of which were hidden from those near and far.
وعلى نحو هذا كان المأمون أيامه. والدليل على ما قلنا فيه ما شاهدنا من رسالته إلى اسحق بن إبراهيم في الفقهاء وأصحاب الحديث، وهو بالشأم. خبر فيها عن عيب واحد واحد، وعن حالته وأموره التي خفيت، أو أكثرها، عن القريب والبعيد.
