This world is a place of trial

This World is the Place of Trial Then Allah tells us that He has made this world a temporary abode, adorned with transient beauty, and He made it a place of trial, not a place of settlement. So He says

﴿إِنَّا جَعَلْنَا مَا عَلَى الاٌّرْضِ زِينَةً لَّهَا لِنَبْلُوَهُمْ أَيُّهُم أَحْسَنُ عَمَلاً ﴾

(Verily, we have made that which is on earth an adornment for it, in order that We may test which of them are best in deeds.) Abu Maslamah narrated from Abu Nadrah from Abu Sa`id that the Messenger of Allah said:

«إِنَّ الدُّنْيَا حُلْوَةٌ خَضِرَةٌ، وَإِنَّ اللهَ مُسْتَخْلِفُكُمْ فِيهَا فَنَاظِرٌ مَاذَا تَعْمَلُونَ، فَاتَّقُوا الدُّنْيَا، وَاتَّقُوا النِّسَاءَ، فَإِنَّ أَوَّلَ فِتْنَةِ بَنِي إِسْرَائِيلَ كَانَتْ فِي النِّسَاء»

(This world is sweet and green, and Allah makes you generations succeeding one another, so He is watching what you will do. Beware of (the beguilements of) this world and beware of women, for the first affliction that Children of Israel suffered from was that of women.) Then Allah tells us that this world will pass away and come to an end, as He says:

﴿وَإِنَّا لَجَاعِلُونَ مَا عَلَيْهَا صَعِيداً جُرُزاً ﴾

(And verily, We shall make all that is on it bare, dry soil.) means, `after having adorned it, We will destroy it and make everything on it bare and dry, with no vegetation or any other benefit.' Al-`Awfi reported from Ibn `Abbas that this means everything on it would be wiped out and destroyed. Mujahid said: "a dry and barren plain.'' Qatadah said, "A plain on which there are no trees or vegetation.''
