Uthman ibn Affan, may Allah be pleased with him, said: I heard the Messenger of Allah, peace and blessings be upon him, say: "A day in the path of Allah is better than a thousand days in other than it."(1)

40 - Chapter: The Virtue of Jihad at Sea

3171 - Muhammad ibn Salamah and al-Harith ibn Miskin informed us, it being read to him while I was listening, from Ibn al-Qasim, who said: Malik narrated to me, from Ishaq ibn Abd Allah ibn Abi Talhah, from Anas ibn Malik, who said: When the Messenger of Allah, peace and blessings be upon him, went to Quba', he would visit Umm Haram bint Milhan, and she would feed him. Umm Haram bint Milhan was the wife of Ubadah ibn al-Samit. The Messenger of Allah, peace and blessings be upon him, entered upon her one day, and she fed him and sat delousing his head. The Messenger of Allah, peace and blessings be upon him, then slept, and afterward woke up laughing. She said: I said, "What makes you laugh, O Messenger of Allah?" He said: "People of my ummah were shown to me as fighters in the way of Allah, sailing in the midst of the sea as kings upon thrones, or like kings upon thrones."

(1) A hasan hadith; its narrators are trustworthy except Abu Salih, the freed slave of Uthman, for he is hasan al-hadith, and the discussion of it has preceded in the hadith before it, and except Abu Ma'n, who is Muhammad ibn Ma'n al-Ghifari, from the people of Madinah, as Ibn Hibban mentioned after the hadith (4609) and al-Hakim 2/68. It is he from whom al-Nasa'i narrated this hadith, and he is not Abu Ma'n Abd al-Wahid ibn Abi Musa, whom al-Mizzi included in his "Tahdhib" among the kunyas, and al-Hafiz Ibn Hajar followed up on him in it and pointed this out. Al-Hafiz Ibn Hajar has included in his "Tahdhib" among the names this Abu Ma'n from whom al-Nasa'i narrated, saying: "Muhammad ibn Ma'n ibn Nadlah ibn Amr al-Ghifari, the grandfather of the one before him, Abu Ma'n, well-known by his kunya." End quote. Al-Mizzi did not include him in his "Tahdhib" among the names, nor did he mention him among the kunyas, but al-Hafiz Ibn Hajar mentioned him in "al-Taqrib" among the kunyas and said of him: acceptable.
The hadith is in the author's "al-Sunan al-Kubra" under number (4364).
Ibn Hibban (4609) and al-Hakim 2/68 also narrated it via two chains, from Abd Allah ibn al-Mubarak, with this chain of transmission, and al-Hakim explicitly named Abu Ma'n, saying: Muhammad ibn Ma'n al-Ghifari, Abu Ma'n. Al-Hakim said: This is a sahih hadith according to the conditions of al-Bukhari, but they did not include it.
