Everything has a measure:
Allah Almighty says:
{...Whoever puts his trust in Allah, He is sufficient for him. Indeed, Allah will surely accomplish His purpose, for Allah has set a destiny for everything.}
[Surat at-Talāq: 3]
Whoever fears Allah and relies upon Him will find His support coming without delay and will not despair of His mercy and help. Relief is sure to come to him, for Allah Almighty is competent over all things.
However, Allah Almighty set a certain measure for everything. It has a specific time, which it cannot miss. So, when something is predestined to happen, none can delay it or bring it forward even for a single hour.
A person may sleep in despair with regard to some distress and then he wakes up to find relief.
{...Allah has full power over all things.}
[Surat al-Kahf: 45]
Distress lasts for a specific time and then goes away. Indeed, Allah Almighty set a measure for everything.
A tree will not bear fruit unless its specific time comes; the sun does not rise before its time; a pregnant woman only gives birth according to a specified term.
{...Allah has set a destiny for everything.}
[Surat at-Talāq: 3]
O Allah,forgive us and show mercy to us; indeed, You are competent over all things.
