What is the degree of authenticity of the hadith: "O Ammar, Gabriel just came to me, and I said: O Gabriel, tell me about the virtues of Omar ibn al-Khattab in heaven. So he said: O Muhammad, if I were to tell you about the virtues of Omar from the time Noah dwelled among his people for a thousand years save fifty, the virtues of Omar would not be exhausted. And indeed, Omar is but one good deed of Abu Bakr's good deeds"?

The hadith narrated by Al-Tabarani and Abu Ya'la, from Ammar ibn Yasir (may Allah be pleased with him), is a weak hadith. Its chain of narration revolves around Al-Walid ibn Al-Fadl Al-Anzi and Isma'il ibn Ubayd Al-Ajali Al-Basri. The imams have judged this hadith to be baseless (batil), fabricated (mawdu'), and a lie (makthub). The virtues of Abu Bakr and Umar (may Allah be pleased with them) are numerous and well-known, and do not require this hadith.
