Allah, the Exalted, informs that Musa and Harun pleaded to Allah, expressing their grievance to him:
﴿إِنَّنَا نَخَافُ أَن يَفْرُطَ عَلَيْنَآ أَوْ أَن يَطْغَى﴾
(Verily, we fear lest he should hasten to punish us or lest he should transgress.) They meant that Fir`awn might seize them unexpectedly with a punishment, or transgress against them by tormenting them, when they actually did not deserve it. Ad-Dahhak reported from Ibn `Abbas that he said that transgress here means, "To exceed the bounds.''
﴿قَالَ لاَ تَخَافَآ إِنَّنِى مَعَكُمَآ أَسْمَعُ وَأَرَى ﴾
(He (Allah) said: "Fear not, verily, I am with you both, hearing and seeing.'') meaning; "Do not fear him (Fir`awn), for verily, I am with you and I hear your speech and his speech as well. I see your place and I see his place as well. Nothing is hidden from Me of your affair. Know that his forehead is in My Hand, and he does not speak, breathe, or use any force, except by My leave and after My command. I am with you by My protection, My help and My support.''
﴿فَأْتِيَاهُ فَقُولاَ إِنَّا رَسُولاَ رَبِّكَ﴾
(So go you both to him, and say: "Verily, we are both Messengers of your Lord...'')
