Asim bin Kulayb reported,

I was sitting with Ali when a man wearing travel clothes came in and asked permission to see him. Ali was speaking with the people and was occupied, so he could not attend to him.Then Ali said, "I once went in to see the Messenger of Allah ﷺ while Ayesha was with him.He asked me, 'How are you and the people of such and such?'I replied, 'Allah and His Messenger know best.'He repeated the question, and I again said, 'Allah and His Messenger know best.'Then he said, 'A people will emerge from the direction of the east who recite the Quran, but it will not pass beyond their throats. They will pass through the religion as an arrow passes through its prey. Among them will be a man with a deformed hand, his hand resembling the breast of an Ethiopian woman.'I ask you by Allah, did I not tell you that among them..."And he went on to mention the hadith in its full length.

عاصم بن كليب عن أبيه قال

كنت جالسا عند علي رضي الله عنه إذ دخل عليه رجل عليه ثياب السفر فاستأذن على علي رضي الله عنه وهو يكلم الناس فشغل عنه فقال علي رضي الله عنه إني دخلت على رسول الله ﷺ وعنده عائشة رضي الله عنها فقال لي كيف أنت وقوم كذا وكذا فقلت الله ورسوله أعلم ثم عاد فقلت الله ورسوله أعلم قال فقال قوم يخرجون من قبل المشرق يقرءون القرآن لا يجاوز تراقيهم يمرقون من الدين كما يمرق السهم من الرمية فيهم رجل مخدج اليد كأن يده ثدي حبشية أنشدكم بالله هل أخبرتكم أن فيهم فذكر الحديث بطوله
