Shahid

How can a person know that the president of his country exists and holds some power in the country eventhough he never met the president face-to-face? Yes, he knows it from the news (tv, radio, newspapers etc) and daily instances (elections, government offices etc).

The same logic applies to Allah's existence. Our heart, intellect and conciousness tell us that Allah rules. Except that Allah's power is limitless and Allah knows every tiny detail of all the creations. Allah knows ourself better than we do and Allah's knowledge is far beyond our comprehension.

When a person realizes that Allah rules and follows Allah's guideline, then he is being an attestant to Allah's authority (shahid). An attestant (shahid) lives a blissful eternal life (in here/dunyaa and hereafter/aakhirah).

Laa haula wa laa quwwata illa bi-Allah.
