Al-Mu'jam al-Awsat 9273 — When the time of death approached Sayyiduna

Al-Sunabihi (may Allah have mercy on him) narrates: When the time of death approached Sayyiduna Ubadah (may Allah be pleased with him), and I was sitting by his head weeping, he asked: "Why are you weeping?" I said: "Why should I not weep, for the benefit that has reached me from you and the good I have gained from you (is about to end)?" He said: "By Allah, I have narrated to you every word I heard from the Messenger of Allah (peace and blessings be upon him) except one, and now I will tell you that too. I heard the Messenger of Allah (peace and blessings be upon him) saying: 'Whoever says "La ilaha illallahu wahdahu la sharika lah" (There is no god but Allah alone, He has no partner), his heart submitting to it and his tongue humbled by it, Allah makes him forbidden for the Fire.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Zayd bin Aslam except his son Abd al-Rahman, and Abu Salih is alone in narrating it."
