Insert your hand into the opening of your garment; it will come out white, without disease. And draw in your arm close to you [as prevention] from fear, for those are two proofs from your Lord to Pharaoh and his establishment. Indeed, they have been a people defiantly disobedient."
Musa's Return to Egypt and how he was honored with the Mission and Miracles on the Way
In the explanation of the previous Ayah, we have already seen that Musa completed the longer and better of the two terms, which may also be understood from the Ayah where Allah says:
فَلَمَّا قَضَى مُوسَى الاٌّجَلَ
(Then, when Musa had fulfilled the term,) meaning, the longer of the two; and Allah knows best.
وَسَارَ بِأَهْلِهِ
(and was traveling with his family,) They said: "Musa missed his country and his relatives, so he resolved to visit them in secret, without Fir`awn and his people knowing. So he gathered up his family and the flocks which his father-in-law had given to him, and set out on a cold, dark, rainy night. They stopped to camp, and whenever he tried to start a fire, he did not succeed. He was surprised by this, and while he was in this state,
نُودِيَ مِن شَاطِئِ الْوَادِ الْأَيْمَنِ فِي الْبُقْعَةِ الْمُبَارَكَةِ مِنَ الشَّجَرَةِ أَن يَا مُوسَىٰ إِنِّي أَنَا اللَّـهُ رَبُّ الْعَالَمِينَ He was called by a voice coming from a side of the right valley in the blessed ground, from the tree, saying" 0 Musa, I am Allah, the Lord of the worlds" - 28:30). This subject was also mentioned in Surahs Taha and An-Naml in the story of Musa (علیہ السلام) . In Surah Taha it is said إِنِّي أَنَا رَبُّكَ (it is Me your Lord - 20:12) and in Surah An-Naml نُودِيَ أَن بُورِكَ مَن فِي النَّارِ (So when he came to it, he was called: "Blessed is the one who is in the fire - 27:8), while in the present Surah (Al-Qasas) it appears as إِنِّي أَنَا اللَّـهُ رَبُّ الْعَالَمِينَ (I am Allah the Lord of the worlds - 28:30). Although the wordings are slightly different here, yet the meanings are almost the same. The incident is related in the words which suited to the situation being described. (کَذا قال الامام). The refulgence that Sayyidna Masa (علیہ السلام) had seen in the form of fire was only in the form of an example (mithali), because it is impossible for a worldly being to see the actual refulgence of Allah Ta` ala. Masa (علیہ السلام) is called لَن تَرَانِي (7:143) (You will never see Me) in respect of actual refulgence.
Moses was in Midian probably for ten years. During this period the former Pharaoh died and another member of the Pharaoh dynasty ascended the throne of Egypt. Then, Moses along with his wife (and, according to the Torah, with two children) left again for Egypt. On the way, he underwent the divine test on Mount Tur (Mount Sinai). God, who directly talked to a man on Mount Sinai, can also directly address all other human beings and apprise them of His will. But this is not the way of God. Direct address means removal of the curtain, while the considerations of human trial demand that the curtain should remain in place. So God reveals His message only to a selected person and causes this message to be delivered indirectly through him to others.
