Abu Huraira told that when one of God’s Messenger’s companion came upon a mountain path containing a small spring of fresh water and was delighted by it, he expressed a desire to withdraw from the people and stay in that path. He mentioned that to God’s Messenger, and he replied, “Do not do it, for when any of you remains in God’s path it is more excellent than prayer in his house during seventy years. Do you not want* God to forgive you and bring you into paradise? Fight* in God's path. He who fights in God's path as long as the time between two milkings of a she-camel will be assured of paradise." *These verbs are in plural. Tirmidhi transmitted it.
