[٢/١١٩] رجال الكشي: قال أبو عمرو: حكى بعض الثقات أن أبا محمد صلوات الله عليه كتب إلى إبراهيم بن عبدة: و كتابي الذي ورد على إبراهيم بن عبدة بتوكيلي إياه لقبض حقوقي من موالي هناك نعم هو كتابي بخطي، أقمته أعني إبراهيم بن عبدة لهم ببلدهم حقا غير باطل، فليتقوا الله حق تقاته و ليخرجوا من حقوقي و ليدفعوها إليه، فقد جوزت له ما يعمل به فيها، وفقه الله ومن عليه بالسلامة من التقصير برحمته
2. [2/119] Rijal al-Kashshi: Abu Amr (al-Kashshi) said: one of the Thiqat relayed to me that Aba Muhammad صلوات الله عليه wrote to Ibrahim b. Abda [to show it to his doubters]: ‘and my letter which was issued to Ibrahim b. Abda [previously] appointing him as my agent to collect my dues from my followers over there – then yes – it is indeed by my own handwriting, I have appointed him – that is Ibrahim b. Abda – for them in their town – this a truth and it is not a falsehood, so they should fear Allah the way He ought to be feared and they should take out my dues and hand it over to him, for I have permitted him what he uses from it, may Allah enable him and favor him with protection from short-coming by His mercy.
