18. " allah (himself) bears witness that there is no god but he, and (so do) the angels and the possessors of knowledge, standing firm for justice; there is no god but he, the mighty, the wise." commentary: by creating a single regularity over the world of existence, allah testifies upon the oneness of his own essence. that is, the existing harmony and order, in the whole creation, is an evidence to the sovereignty of only one power over existence. in other worlds, allah informs of his oneness through the wonders of creation and his wise providence, which are like the examples of life. allah calls the creation of the creatures as a witness to his own unity. by the way, he causes to understand that the phenomena he brings into existence are so that none is able to generate even one of them. " allah (himself) bears witness that there is no god but he, ..." by observing the wonders and greatness of power, angels bear witness to the unity of allah. those possessed of knowledge, /'ulul-`ilm/, who know, and it has been proved to them, that none is able to bring the wonders of the world of creation into existence but he, bear witness to the oneness of his essence, too. this fact must also be noticed that though the phrase: ` the possessors of knowledge ' refers to all scientists and knowledgeable ones in general, according to some islamic narrations, the objective meaning of it is prophets and the imams of right guidance (a.s.).1 "...and (so do) the angels and the possessors of knowledge, standing firm for justice; ..." and, angels testify that there is no god save the one, allah, by whom justice is firm. "...there is no god but he, the mighty, the wise." it is he the one, and none else, who gives sustenance, treats his servants justly, and there is no inequity in his affairs. 1 al-burhan, vol. 1, p. 273
