Surah Al Kahf- Ayah No 26

Assalam o Alaikum. Juma Mubarak. On this blessed day, let's seek refuge from greatest fitn through Al Kahf (The Cave) of protection. Often people ask, what is the relationship of Al Kahf and its four stories with Dajjal. For very detailed account, you might have to wait. For basic understanding, please go through the link below:

Start of this Ayah is again powerful reminder that only Allah knows the whole Truth. It also gives an impression that 309 lunar years mentioned in previous Ayah might be a statement of the popular Christian tradition on the topic. And actual knowledge of everything is with the Knower of everything. The statement is further qualified in next line that unseen knowledge of the universe between Heavens and Earth rests with Allah swt only. It gives us two lessons to take home. One that Allah's swt emphasis of knowing all must be paid heed to. Even a dead leaf from a tree in Delta of Amazon falls with knowledge of Allah. With his knowledge 100,000 miles long veins in human body flow or get blocked. These are just samples of details/vastness of His Knowledge. Instead of daring Allah by naming vessels as 'Challenger' which lasted for only 73 seconds, we should submit to His knowledge. Imagine sitting outside milkyway looking down upon a spacecraft crossing just one orbit in Solar system from earth to Mars. It will look like a child learning to take a step  or two. Please do look up in Ar Rehman, the challenge thrown by the Lord in 55:33. Just to remind in Allah's words,'اُوْتِیْتُمْ مِّنَ الْعِلْمِ اِلَّا قَلِیْلً'،'And mankind have not been given of knowledge except a little.' 17:85 So, all our knowledge as specie from inception till the D Day shall accumulative be 'little' when compared with the 'total knowledge' out there. Secondly, don't get into the fuss of numbers, just focus on the message. Even if our heroes, Al Kahf Boys slept for 409 years or 509 years, we only need to understand that Allah swt controls everything. If He can create the Physics that we know of, He can suspend its laws whenever and however He wants.

No wonder, He continues discourse in exclamation that (He swt is) how seeing and how listening. Careful people, He knows it already, it is a word of caution for us who sometimes lose this sense of being seen, heard and recorded. 

Last part of this Ayah is the best example of 'Unity of Command', i.e. Oneness and that too without any partnership. Allah swt shows His affection by prompting that for us there could be no better friend than Him. However, we must keep in mind that He is the King whose Kingdom extends yonder than our imagination, hence, He wouldn't share His authority with anyone or let anyone use/misuse His authority. It is perfectly logical, if there are any heir to any throne, there is divide in heirs and followers. It warrants reciting:

قُلْ هُوَ اللّٰهُ اَحَدٌۚ(۱)اَللّٰهُ الصَّمَدُۚ(۲)لَمْ یَلِدْ ﳔ وَ لَمْ یُوْلَدْۙ(۳)وَ لَمْ یَكُنْ لَّهٗ كُفُوًا اَحَدٌ۠(۴)
