Were this world worth a wing of a mosquito in the sight of Allah, He would not have given …

This Hadīth indicates the insignificance of this worldly life in the sight of Allah, and that it has no value. If it did have any value in Allah's sight, then He wouldn't have allowed a disbeliever to have a sip of water, let alone give him provisions and joyful pleasures. This worldly life is worthless in the sight of Allah, contrary to the Hereafter which is the eternal abode of bliss, prepared for the believers alone, apart from the disbelievers. For this reason, the believers should realize the reality of this worldly life and not attach themselves to it, for it is a passage way and not the permanent residence.

They should only take from this worldly life what would benefit them in the Hereafter; Allah says in the Qur'an: {And whatever you have been given is an enjoyment of the life of this world and its adornment, and that which is with Allah is better and everlasting. Do you not comprehend? Is he whom We have promised an excellent promise (Paradise) which he will find true like him whom We have made to enjoy the luxuries of the life of this world, then on the Day of Resurrection, he will be among those brought to be punished in the Hellfire?} [Sūrat al-Qasas: 60-61]
