قَالَ كَلَّ
...
(Allah) said: "Nay!..."
Allah told him: do not be afraid of anything like that.
This is like the Ayah,
سَنَشُدُّ عَضُدَكَ بِأَخِيكَ وَنَجْعَلُ لَكُمَا سُلْطَـناً
...
Allah said: "We will strengthen your arm through your brother, and give you both power, (meaning, proof);
...
فَلَ يَصِلُونَ إِلَيْكُمَا بِـْايَـتِنَأ أَنتُمَا وَمَنِ اتَّبَعَكُمَا الْغَـلِبُونَ
... so they shall not be able to harm you, with Our signs, you two as well as those who follow you will be the victors. (28:35)
...
فَاذْهَبَا بِأيَاتِنَا إِنَّا مَعَكُم مُّسْتَمِعُونَ
Go you both with Our signs. Verily, We shall be with you, listening.
This is like the Ayah,
إِنَّنِى مَعَكُمَأ أَسْمَعُ وَأَرَى
I am with you both, hearing and seeing. (20:46)
Meaning, `I will be with you by My protection, care, support and help.'
فَأْتِيَا فِرْعَوْنَ فَقُولاَأ إِنَّا رَسُولُ رَبِّ الْعَالَمِينَ
