Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: One of the Companions of the Prophet (peace and blessings be upon him) passed by a mountain pass in which there was water, and he liked its pleasantness. He thought: "If I were to separate myself from people and settle in this mountain pass (that would be fitting), but I will not do so until I seek permission from the Messenger of Allah." He mentioned this to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said: "Do not do so, for one of you standing in the way of Allah is better for him than standing (or offering voluntary prayers) in his own house for sixty years (the narrator is in doubt about a word here). Whoever fights in the way of Allah for as long as it takes to milk a she-camel, Paradise becomes obligatory for him."
Al-Bazzar recorded it, and its narrators are thiqat (trustworthy). The hadith narrated from Sayyiduna Imran bin Husayn (may Allah be pleased with him) about the virtue of a man standing in the battle line for fighting will come later.
