In Surah Rum verse 43, Allah (swt) tells "Then set your face upright towards the established religion before that day comes from God, when there will be no escape". We are told to turn to Deen before the Day of Judgement when people will be separated. The verse tells mankind to search for that perfect deen.

If we look at the world around us, we commonly see an object whose recognition comes through it's individual characteristics. If you remove these characteristics, the object will loose its identity, it will become unrecognisable.

There exist some things in nature whose recognition requires no identification, for example the sun coming out, its very presence serves as its identification, it requires no further verification. In some cases, something has no identity, it does not present itself, rather it depends upon others to present it, for example adalat (justice), ibadat (worship) are concepts which on their own have no identification, they have no physical presence, you can not just point at something and conclude this is adalat.
