Purpose & Stroy

The Messenger of Allah ﷺ said:

“When the human being dies, his deeds end except for three: ongoing charity, beneficial knowledge, or a righteous child who prays for him.”

This notebook/wiki is a humble effort to share beneficial knowledge. May Allah accept it.

The idea started during my university studies while preparing for exams. As I worked to truly understand my courses, I naturally started creating summaries, cheat sheets, and personal notes. I also used AI to simplify difficult concepts. Over time, this grew into a large and organized collection of knowledge.

At some point, I paused and reflected. I am a Muslim, and my religion encourages benefiting others. That moment changed my intention. Instead of keeping this work private, I decided to put in extra effort to refine it; editing, organizing, and simplifying everything so it could be useful and understandable for others.

With a renewed niyyah for the sake of Allah, and with the responsibility that comes with it; itqan (excellence) and ihsan (doing things well), this project became a way to document and share everything I learn throughout my journey in software engineering.

May Allah accept this work, place barakah in it, and grant us all tawfiq.
