The knowledge of Islamic monotheism is the most noble of all branches of knowledge. It also has the greatest worth. In addition, it is the most important of all obligations. It is all of these because it is knowledge of Allah, His names, His attributes and His rights upon His servants. Furthermore, it is the opening to the path that leads to Allah and the foundation of His Sacred Laws.
For these reasons, all of the messengers called to this knowledge and understanding. Thus, Allah says,
“And We did not send any Messenger before you (O Muhammad but We inspired him (saying): There is none worthy of worship but I (Allah), so worship Me (Alone and none else).” [Surah al‐Anbiyaa (21):25].
Allah Himself bears witness to His own Oneness. The angels also bear witness to that as well as the people of knowledge. Allah says,
“Allah bears witness that none has right to worshiped but He, and the angels, and those having knowledge (also give this witness); established on justice. None has right to worshiped but He, the All‐Mighty, the All‐Wise.” [Surah Ali‐Imraan 3:18].
Since this is the place and status of Islamic monotheism, it becomes a must upon every Muslim to attend to it by learning it, teaching it, pondering over it and believing in it. In this way, his religion may be built upon a sound foundation of conviction, confidence and submission and he may happily reap the fruits and results of this Islamic monotheism.
