Majma al-Zawaid — Hadith 14799

In one narration the words are: "On that same night Sayyiduna Yusha' bin Nun (peace be upon him), the companion of Sayyiduna Musa (peace be upon him), was martyred."
Al-Tabarani recorded it in al-Mu'jam al-Awsat, and in al-Mu'jam al-Kabir in abridged form; however, he narrated these words: "the twenty-seventh night of Ramadan."
Abu Ya'la also recorded it in abridged form, and al-Bazzar recorded something similar; however, he narrated these words: "The Prophet (peace and blessings be upon him) would give him the banner; when battle broke out, Sayyiduna Jibril (peace be upon him) would fight on his right," and in it he narrated these words: "It was the twenty-first night of Ramadan" (when Sayyiduna Ali (may Allah be pleased with him) was martyred).
Ahmad recorded it in a greatly abridged form. The chain of Ahmad, some of the routes of al-Bazzar, and the chain of al-Tabarani in al-Mu'jam al-Kabir are all hasan (good).
