Silsilat al-Ahadith al-Sahihah

One of the companions of the Messenger passed by a valley in which there was a small spring of sweet water, and its fragrance greatly pleased him. He (thought to himself): If I separate myself from the people and devote myself in this valley... But first, I will consult the Messenger of Allah (peace and blessings be upon him). When he mentioned this to the Prophet (peace and blessings be upon him), he said: "Do not do so, for your staying in the path of Allah is better than sixty years of individual prayer. Do you not wish that Allah should forgive you and admit you to Paradise? Strive in the path of Allah; whoever strives in the path of Allah for the duration between two milkings of a she-camel, Paradise becomes obligatory for him."
