Their three questions, which are known as "the three questions of the grave" are :
1. Who is your Lord?
2. What is your Religion?
3. Who is your Prophet?
As such, it is obligatory that every Muslim man and woman have a firm, if not basic, understanding of these three questions as the foundation of his/her Aqeedah.
• The FIRST is Knowledge of Allah :
It is obligatory upon every Muslim, male or female, to know their Lord by His Essence, His Names and Attributes, His Actions and that,
“There is nothing like unto Him. And He is the All-Hearing, the All-Seeing.” [Surah Ash-Shooraa 42:11]
The servant must know that Allaah سبحانه و تعالى is his Creator (khaaliq), Sustainer (raaziq) and the controller of his affair. Rather, He controls the entire universe.
He is deserving of that, because He is to be worshiped alone without any associate. And every act of worship that is directed to other than Him is a nullified act of worship.
And the servant must believe that He has Beautiful Names and Lofty Attributes which have come in the Book of Allah and in the Sunnah of His Messenger صلى الله عليه وسلم.
What every Muslim must know and believe about Allah سبحانه و تعالى forms the basis of Tawheed.
• The SECOND is Knowledge of the Religion of Islam with It's Evidences :
This is a wide topic, because the Religion of Islam comprises everything that Allah ordained for the world of mankind and Jinn from the duties, obligations, prohibitions and other than that from the Shari’ah.
Due to this, Allaah said concerning His Right,
“Verily, the Religion with Allah is Islam.” [Surah Aali-’Imran 3:19]
This knowledge does not mean that the average Muslim must have in-depth knowledge of the various Shari'ah and Fiqh rulings. No, what is meant here is that the average Muslim must have knowledge about the basic matters of Islam as it relates to him.
He must know what is Tawheed and its categories. He must know what Islam means and its pillars. He must know what is Eeman and its pillars. And he must know the evidences for them. He must know the conditions and nullifiers for the various acts of worship such as prayer, fasting etc... and how to perform them correctly. And etc...
Therefore, the Muslim must know his religion. It is not sufficient to be a Muslim in just name only.
• The THIRD is Knowledge of the Prophet :
From the obligations from which no one is excused from being ignorant of is knowledge of the Prophet صلى الله عليه وسلم and knowledge of what the Prophet صلى الله عليه وسلم came with.
It is not sufficient for the Muslim, male or female, that everyone from amongst them says, ‘I know about the Messenger of Allah, and he is Muhammad Ibn ’Abdullah.’ This is not sufficient.
One must know that he was sent by Allah and that Allah revealed a Book to him and commanded him to call to and explain this Book to the whole of mankind and jinn.
So due to this, knowledge of the Prophet صلى الله عليه وسلم means that the Muslim must know him as a person; who he was, where he came from and how he lived his life i.e. have a basic understanding of his Seerah (biography), the Book he came with, and the Sunnah that he taught.
All Praise and Thanks is due to Allah Alone, the Lord of the Worlds and may He forgive us our sins and make us among His sincere believers.
May the peace and blessings of Allah be upon our Prophet Muhammad, his family and his Companions. Aameen.
