For preserving time, I say to everyone who wants that Allah blesses their life, my advice is:
Let the very first thing you think about be the rights of Allah (Exalted be He). In order to save your time, fulfill the rights of Allah (Exalted be He)
For example, the five (daily) prayers, they have specific timings. So, if you want that Allah blesses your time,
once the obligatory prayer is called out, think about nothing but fulfilling the right of Allah (Exalted be He).
No matter how busy you may be, fulfill the right of Allah. When you start you day, fulfill the rights of Allah.
They are successful who don’t just think of the prayer when its time is due or when they hear the adhan.
Yet, they are preoccupied with prayer, hours before its time becomes due.
Some who are more successful as they have reached the degree of Ribat
which is waiting for the next prayer after observing a prayer
A servant will not be granted blessing in their time unless they observe the prayers Allah prescribed.
For whoever wants Allah to bless their life and time
the first thing to think about is the Five Daily Prayers
When you look at your day and the time spent in salah, you have offered it for the sake of Allah,
and prayed as per Allah’s orders; you’ll find blessings in all your affairs.
