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."
Ibn ‘Abbas reported God's Messenger as saying, “There are two eyes which will never be touched by hell, an eye which weeps from fear of God and an eye which spends the night on guard in God’s path."
Abu Huraira reported God’s Messenger as saying, “No one who weeps from fear of God will go into hell till the milk returns to the udder, and no servant of God will experience both dust in God’s path and the smoke of jahannam."
Tirmidhi transmitted it, and Nasa'i added in another version, “ever in a Muslim’s nostrils." In another by him he added, “ever in the belly of a servant of God; and stinginess and faith will never be combined in the heart of a servant of God."
