فَأْتِيَاهُ فَقُولآ إِنَّا رَسُولاَ رَبّـِكَ فَاَرْسِل مَعَنَا بَنِي إِسْرآئِيلَ وَلاَ تُعَذّ‌ِبْهُمْ قَدْ جِئْناكَ بِاَيَةٍ مّـِن رَّبّـِكَ وَالسَّلاَمُ عَلَي مَنِ اتَّبَعَ الْهُدَي

إِنَّا قَدْ اُوحِيَ إِلَيْنَآ أَنَّ الْعَذَابَ عَلَي مَن كَذَّبَ وَتَوَلَّي

47. “So go you both unto him and say: ‘(O Pharaoh!) Verily we are Messengers from your Lord. Send forth, therefore, the Children of Israel with us and do not chastise them. We have brought you a sign (a miracle) from your Lord, And peace will be upon him who follows the guidance!”
48. “Verily it has been revealed unto us that the chastisement will be upon him who rejects (the Divine Signs) and turns away.”

Since teaching and guidance of cruel leaders to the right way had been an important and very hard task, Allah has repeated the command of going toward Pharaoh. Allah has stated for them the method of their invitation at the presence of Pharaoh in five short, conclusive, and expressive sentences. One of them concerns the main mission; the second states the content of the mission; the third mentions the reason and the evidence of their mission; the fourth is the encouragement of those who accept the invitation; and the fifth is a threat against the opponents of it.

At first it says:

Then it continues saying:

After that, the revelation points to their evidence by saying:

Therefore, as intellect directs, it is necessary that you ponder over our words and if they are right, you ought to accept them. Then, as an encouragement of the believers, it adds:

This phrase may point to another meaning, too. It may say that safety and prosperity both in this world and the Hereafter belongs to those who follow the godly guidance. They will be free from disquiets, offences, Divine painful punishments, and social and personal difficulties of life. This is, in fact, the result of Moses’ invitation. At last, in the next verse, Moses and Aaron are told to say to Pharaoh the evil end of his disobedience from this invitation, by saying:

This is a fact that ought to be said to Pharaoh manifestly.
