Hadith 17:363
Hafs ibn Ghiyath narrated to us, from Ash'ath, from Abu Burdah, who said: I entered the mosque of Medina, and there was Abdullah ibn Salam. I greeted him, then I sat down. He said: "O son of my brother, you have sat down while we were intending to stand up."
حدثنا حفص بن غياث عن أشعث عن أبي بردة قال دخلت مسجد المدينة فإذا عبد الله بن سلام فسلمت ثم جلست فقال يا بن أخي إنك جلست ونحن نريد القيام
