Basics- Revisiting and Revising The Most Important Fundamentals- [The Greatest And Loftiest Pillar of Islaam]
In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
The greatest and loftiest in status amongst the five pillars of Islaam is the testimony “There is no deity that has the right to be worshipped except Allaah and Muhammad [peace and blessings of Allaah be upon him] is the Messenger of Allaah”. This is why the Messenger [peace and blessings of Allaah be upon him] mentioned it first in the hadeeth, “Islam is built on five pillars: to testify that there is no deity that has the right to be worshipped except Allaah and Muhammad is the Messenger of Allaah”. So, the testification that Allaah is the only deity that has the right to be worshipped and the testification regarding the Messengership of Allaah’s Prophet is the greatest pillar and foundation of Islaam; rather it is the foundation of the religion.
“Laa Ilaaha Illal laah -None has the right to be worshipped except Allaah” is the greatest, most virtuous and the loftiest statement without exception. It is the best statement by way of which Allaah is remembered. The Prophet [peace and blessings of Allaah be upon him] said, “The best Dkir [remembrance of Allaah] is ‘Laa ilaaha illal laah – There is no deity that has the right to be worshipped except Allaah'”. [Reported by Tirmidhee and declared Hasan by Imaam Al-Albaanee in As-Saheehah 1497]
The Prophet [peace and blessings of Allaah be upon him] also said, “The best supplication on the day of Arafah and the best of that which I and the Prophets before me have ever uttered is: [لا إلهَ إلاَّ اللَّه وحْدهُ لاَ شَرِيكَ لهُ، لَهُ المُلْكُ، ولَهُ الحمْدُ، وَهُو عَلَى كُلِّ شَيءٍ قَدِيرٌ – There is no deity that has the right to be worshipped except Allaah, He is One and He has no partner; His is the (absolute) Sovereignty and to Him belongs all praise, and He is Able to do all things”. [Musnad Ahmad 6961. Declared authentic by Imaam Al-Albaanee in As-Saheehah 1503]
This is why Allaah [The Exalted] said: [وَمَآ أَرۡسَلۡنَا مِن قَبۡلِكَ مِن رَّسُولٍ إِلَّا نُوحِىٓ إِلَيۡهِ أَنَّهُ ۥ لَآ إِلَـٰهَ إِلَّآ أَنَا۟ فَٱعۡبُدُونِ – And We did not send any Messenger before you (O Muhammad ) but We inspired him (saying): Laa ilaaha illaa Ana [none has the right to be worshipped but I (Allah)], so worship Me (Alone and none else)]. [Surah Al-Anbiyaa. Aayah 25]
It is the essence of the call of the Messengers. The first thing their people heard from them was: [ٱعۡبُدُواْ ٱللَّهَ مَا لَكُم مِّنۡ إِلَـٰهٍ غَيۡرُهُ – Worship Allah! You have no other Ilaah (deity) but Him]. [Surah Al-A’raaf. Aayah 59]
