Musa's fear of Fir`awn and Allah's strengthening Him

Allah, the Exalted, informs that Musa and Harun pleaded to Allah, expressing their grievance to him:

إِنَّنَا نَخَافُ أَن يَفْرُطَ عَلَيْنَآ أَوْ أَن يَطْغَى

Allah said,إِنَّنِي مَعَكُمَا أَسْمَعُ وَأَرَ‌ىٰ "I am surely with you both. I hear and I see." - 20:46) Here the word "with you" is used in the sense of divine help and support which human senses cannot perceive.

Sayyidna Musa (علیہ السلام) called upon the Pharaoh to embrace the True Faith and also to deliver the Bani Isra'il from bondage
