As it was mentioned in the last post, the progeny of Prophet Yusuf (as) lived in Egypt until the time of Prophet Musa (as). The descendents of Yusuf (as) were known as Banu Isra'il (the Children of Israel, Israel being Prophet Yaqoub). Banu Isra'il had faced persecution at the hands of the Egyptians and during the time of Musa (as) this persecution was at its height.
Allah told his prophet Musa (as) to give dawah (invitation to Islam) to Firawn (Pharoah) and his people. However, despite being shown clear signs by Musa (as) and being sent ayaat (signs) by Allah, they refused to believe.
Due to the disbelief of Firawn and his people Allah revealed to his Prophet Musa (as) to take the Banu Isra'il out of Egypt and towards the Holy Land where they would be free from tyranny and oppression. The story of how Musa (as) and the Banu Isra'il were persued by the army of Firawn behind them and were faced with the Red Sea in front of them is well-known. Allah says in the Quran:
"And We revealed to Musa: 'Strike the sea with your staff'. It parted- each side like a mighty mountain- and We brought the others to that place: We saved Musa and all his companions, and drowned the rest. There truly is a sign in this, though most of them do not believe: your Lord alone is the Almighty, the Merciful". (Surah Al Shu'ara: 63- 68)
Although Musa (as) and the Banu Isra'il escaped from Egypt, they did not enter the Holy Land in the lifetime of Musa (as) as a punishment of Allah on Banu Isra'il because of their disobedience. The next few posts will cover the issue of disobedience in more detail, inshaAllah.
