Az-Zukhruf 43:48

<h2>Musa was sent with the Message of Tawhid to Fir`awn and His Chiefs</h2><p>Here Allah tells us about His servant and Messenger Musa, peace be upon him, and how He sent him to Fir`awn and his chiefs. That is, his governors, ministers, leaders and followers among the Egyptians and the Children of Israel. Allah sent him to call them to worship Allah alone, with no partner or associate, and to forbid them from worshipping anything other than Him. He sent him with mighty signs, such as his hand and his staff, other signs such as the flood, locusts, Qummal, frogs and blood, and the loss of their crops and lives. Yet despite all that they remained arrogant and stubbornly refused to follow him; they rejected his message and made fun of it, and laughed at the one who had brought it.</p><div class="arabic uthmani">وَمَا نُرِيِهِم مِّنْ ءَايَةٍ إِلاَّ هِىَ أَكْبَرُ مِنْ أُخْتِهَا</div><p>(And not an Ayah We showed them but it was greater than its fellow preceding it,) but despite that they would not give up their sin, misguidance, ignorance and confusion. Every time one of these signs came to them, they would go and implore Musa, saying,</p><div class="arabic uthmani">يأَيُّهَ السَّاحِرُ</div><p>("O you sorcerer!...") …

And every token that We showed them was greater than its sister (token), and We grasped them with the torment, that haply they might turn again.

We showed them Sign after Sign, each greater than its fellow, and We seized them with Punishment, in order that they might turn (to Us).

And not an Ayah (sign, etc.) We showed them but it was greater than its fellow, and We seized them with torment, in order that they might turn [from their polytheism to Allah's Religion (Islamic Monotheism)].

Each sign We showed them was more marvelous than its counterpart. And We afflicted them with the plagues, so that they may repent.
