Narrated Ibn `Abbas: The Prophet said, "There are two blessings which many people lose: (They are) Health and free time for doing good."

Narrated Anas: The Prophet said, "O Allah! There is no life worth living except the life of the Hereafter, so (please) make righteous the Ansar and the Emigrants."

Narrated Sahl bin Sa`d As-Sa`idi: We were in the company of Allah's Apostle in (the battle of) Al-Khandaq, and he was digging the trench while we were carrying the earth away. He looked at us and said, "O Allah! There is no life worth living except the life of the Hereafter, so (please) forgive the Ansar and the Emigrants."

Its explanation, and Allah the Exalted has said (in Surah Al-Hadid): "Indeed, the life of this world is nothing but play and amusement, and adornment, and boasting among yourselves, and rivalry in increase of wealth and children. Its example is like that of rain whose [resulting] plant growth pleases the tillers; then it dries and you see it turning yellow; then it becomes [scattered] debris. And in the Hereafter there is severe punishment for the disbelievers, and forgiveness from Allah and His pleasure for the believers. And the life of this world is nothing but the enjoyment of delusion."

Narrated Sahl: I heard the Prophet saying, "A (small) place equal to an area occupied by a whip in Paradise is better than the (whole) world and whatever is in it; and an undertaking (journey) in the forenoon or in the afternoon for Allah's Cause, is better than the whole world and whatever is in it."

Narrated Mujahid: `Abdullah bin `Umar said, "Allah's Apostle took hold of my shoulder and said, 'Be in this world as if you were a stranger or a traveler." The sub-narrator added: Ibn `Umar used to say, "If you survive till the evening, do not expect to be alive in the morning, and if you survive till the morning, do not expect to be alive in the evening, and take from your health for your sickness, and (take) from your life for your death."

And Allah the Exalted has said «فمن زحزح عن النار وأدخل الجنة فقد فاز وما الحياة الدنيا إلا متاع الغرور» : "So whoever is saved from the Fire and admitted to Paradise, he indeed is successful. And the life of this world is nothing but the enjoyment of delusion." And (in Surah Al-Hijr) He said «ذرهم يأكلوا ويتمتعوا ويلههم الأمل فسوف يعلمون» : "O Prophet! Leave the disbelievers to eat and enjoy themselves, and let (false) hope deceive them, for soon they will know, when death comes upon them suddenly." Ali (may Allah be pleased with him) said: The world is turning away and the Hereafter is approaching. Among mankind are those who seek the world and those who seek the Hereafter. So be among the seekers of the Hereafter, not the seekers of the world, for today is for deeds and not for reckoning, and tomorrow will be for reckoning and not for deeds. In Surah Al-Baqarah, the word «بمزحزحه» means «بمباعده» , meaning "the remover."

Narrated `Abdullah: The Prophet drew a square and then drew a line in the middle of it and let it extend outside the square and then drew several small lines attached to that central line, and said, "This is the human being, and this, (the square) in his lease of life, encircles him from all sides (or has encircled him), and this (line), which is outside (the square), is his hope, and these small lines are the calamities and troubles (which may befall him), and if one misses him, an-other will snap (i.e. overtake) him, and if the other misses him, a third will snap (i.e. overtake) him."

Narrated Anas bin Malik: The Prophet drew a few lines and said, "This is (man's) hope, and this is the instant of his death, and while he is in this state (of hope), the nearer line (death) comes to Him."

Because Allah has said «‏‏‏‏أولم نعمركم ما يتذكر فيه من تذكر وجاءكم النذير‏» "Did We not give you a life long enough so that whoever would receive admonition could receive it? And the warner came to you, yet you did not take heed."
