Qur'an, Al-'Ankabut, Surah 29:63-64
If you were to ask the animals, who sends rain from the sky to enliven the barren earth, they would reply: 'God.' So you should proclaim God's praise. Yet most people are too stupid to do this.
The life of this world is merely a sport; it is only an idle pastime. The true life is the life to come—if you only knew it.
