Surat Al A`raf: (128-129)

{قَالَ مُوسَى لِقَوْمِهِ اسْتَعِينُوا بِاللّهِ وَاصْبِرُواْ إِنَّ الأَرْضَ لِلّهِ يُورِثُهَا مَن يَشَاءُ مِنْ عِبَادِهِ وَالْعَاقِبَةُ لِلْمُتَّقِينَ} [الأعراف: 128]

128- Moses said to the Children of Banu Israel while preaching and strengthening their faith: Seek the help, power, and success from Allah for He is You Lord, and observe patience on their threats, for the earth belongs to Allah and Egypt is part of it, so it does not belong to the Pharaoh, but to Allah. For this reason, Allah grants His Land to whomever He wants of His Servants, and the good final destination is for the pious believers not for oppressors.

{قَالُواْ أُوذِينَا مِن قَبْلِ أَن تَأْتِينَا وَمِن بَعْدِ مَا جِئْتَنَا قَالَ عَسَى رَبُّكُمْ أَن يُهْلِكَ عَدُوَّكُمْ وَيَسْتَخْلِفَكُمْ فِي الأَرْضِ فَيَنظُرَ كَيْفَ تَعْمَلُونَ} [الأعراف: 129]

129- The Children of Israel said to their Prophet Moses (peace be upon him): We were oppressed and tortured before you have been sent as a Messenger and we are still being tortured after your mission.

He said: To them: Your Lord would eradicate your enemy who has terrified and threatened you and make you their successors in Egypt so that He would try you and see what shall you do after victory; would you be grateful or ungrateful?
