Ammar came in to see Ali, who greeted him saying, "Welcome to the good and purified one. I heard the Messenger of Allah ﷺ say, 'Ammar has been filled with faith to the very marrow of his bones.'"
حدثنا نصر بن علي الجهضمي حدثنا عثام بن علي عن الأعمش عن أبي إسحق
دخل عمار على علي فقال مرحبا بالطيب المطيب سمعت رسول الله ﷺ يقول ملئ عمار إيمانا إلى مشاشه
Its isnad is daif. Ibn Abu Shaybah related it in Al-Musannaf (12/120,121), and Ibn Hibban graded it sahih. Abu Ishaq and his student both used ambiguous transmission wording (anana), as mentioned previously, hadith 46. It has daif corroborating narrations in Nasai, Al-Hakim, and others. And Allah knows best.
