And, indeed We gave Our grace to Musa and Harun. And We saved them and their people from the great distress, And helped them, so that they became the victors;
Allah tells us how He blessed Musa and Harun with Prophethood and how He saved them, along with those who believed, from the oppression of Fir`awn and his people, who had persecuted them by killing their sons and sparing their women, and by forcing them to do the most menial tasks, then ultimately He caused them to prevail over them and to seize their lands and their wealth and all that they had spent their entire lives amassing. Then Allah revealed to Musa the Clear and Mighty Book, which is the Tawrah, as Allah says;
وَلَقَدْ ءَاتَيْنَا مُوسَى وَهَـرُونَ الْفُرْقَانَ وَضِيَأءً
And indeed We granted to Musa and Harun the criterion (of right and wrong), and a shining light (21;48)
And Allah says here;
وَاتَيْنَاهُمَا الْكِتَابَ الْمُسْتَبِينَ
