Time management is a key for successful life not only here but also hereafter.
Life management is very important in Islam as it enables us to utilize our limited time on this planet for the aims of our creation. Worships in Islam are time bound which shows the importance of time management. Islam teaches to organize our time between working for livelihood and preparing for our hereafter future and resting.
We have many Quranic verses and authentic Hadeeth guiding us to the importance of time management.
Wassalam.
