I came to Madinah and asked Allah to grant me a righteous companion to sit with, so He granted me Abu Hurayra. I sat with him and said to him, "I asked Allah to grant me a righteous companion to sit with, and I have been blessed with you."He asked me, "Where are you from?"I replied, "I am from the people of Kufa. I have come seeking and pursuing what is good."He said, "Do you not have among you Saad bin Malik, whose supplications are answered, and Ibn Masud, who carried the water for the Messenger of Allah's ﷺ purification and his sandals, and Hudhayfa, the keeper of the Messenger of Allah's ﷺ secret, and Ammar, whom Allah granted refuge from Satan through the tongue of His Prophet, and Salman, the man of the two books?"Qatada said, "The two books are the Gospel and the Furqan."He said, this is a hasan sahih gharib hadith. Khaythama is the son of Abdul-Rahman bin Abu Sabra. He was simply attributed to his grandfather.
حدثنا الجراح بن مخلد البصري حدثنا معاذ بن هشام حدثني أبي عن قتادة
أتيت المدينة فسألت الله أن ييسر لي جليسا صالحا فيسر لي أبا هريرة فجلست إليه فقلت له إني سألت الله أن ييسر لي جليسا صالحا فوفقت لي فقال لي ممن أنت قلت من أهل الكوفة جئت ألتمس الخير وأطلبه قال أليس فيكم سعد بن مالك مجاب الدعوة وابن مسعود صاحب طهور رسول الله ﷺ ونعليه وحذيفة صاحب سر رسول الله ﷺ وعمار الذي أجاره الله من الشيطان على لسان نبيه وسلمان صاحب الكتابين قال قتادة والكتابان الإنجيل والفرقان قال هذا حديث حسن صحيح غريب وخيثمة هو ابن عبد الرحمن بن أبي سبرة إنما نسب إلى جده
[Its isnad is daif] and its chain is daif due to Qatada's use of ambiguous transmission wording ("an"), though the hadith has meaning-based corroborating witnesses.
