He stayed there for ten years before moving on to "Tuwa", a valley at the foot of a mountain At-Tur in Sinai. Here, Musa (SAW) was given the divine guidance by Allah (SWT), and was selected as Allah's Messenger. Sura Qasas (28:30)
But when he came to the (Fire), a voice was heard from the right bank of the valley, from a tree in hallowed ground: "O Musa ! Verily I am Allah, the Lord of the worlds....
Allah (SWT), bestowed on Musa (SAW) two signs. A "Stick" which when thrown down would turn into a living serpent and to make his hand shine, after it was drawn out from under his arm Sura Taha (20:17-22) Allah (SWT) said:
"And what is that in thy right hand, O Musa?"
He said, "It is my rod: on it I lean; with it I beat down fodder for my flocks; and in it I find other uses."
Allah (SWT) said, "Throw it, O Musa!
He threw it, and behold! it was a snake, active in motion.
Allah (SWT) said, "Seize it, and fear not: We shall return it at once to its former condition"...
Now draw thy hand close to thy side: It shall come forth white (and shining), without harm (or stain),- as another Sign,
Allah (SWT), commanded Musa (SAW) to go to Fir'awn and invite him to "Tawhid"Sura Taha (20:42-44).
Go, thou and thy brother, with My Signs, and slacken not, either of you, in keeping Me in remembrance.
"Go, both of you, to Pharaoh, for he has indeed transgressed all bounds; "But speak to him mildly: perchance he may take warning of fear (Allah)"
He begged Allah (SWT), to make his brother Harun (Aaron) his helper and Allah (SWT), granted his prayer Sura Taha (20:24-36)
"Go thou to Pharaoh for he has indeed transgressed all bounds."
Musa (SAW) said: "O my Lord! expand me my breast; "Ease my task for me; "And remove the impediment from my speech, "So they may understand what I say: "And give me a Minister from my family, "Harun, my brother; "Add to my strength through him, "And make him share my task: "That we may celebrate thy praise without stint, "And remember thee without stint: For thou art He that (ever) regardeth us."
Allah (SWT) said: "Granted is thy prayer, O Musa!"
Musa (SAW) to save the Israelites from the oppression of the Egyptians. Fir'awn refused to let the Israelites go Sura Taha (20:47-54).
"So go ye both to him, and say, 'Verily we are apostles sent by thy Lord: Send forth, therefore, the Children of Israel with us, and afflict them not: With a Sign, indeed, have we come from thy Lord! and Peace to all who follow guidance!
"'Verily it has been revealed to us that the Penalty (awaits) those who reject and turn way.'"
When this message was (delivered,) (Pharaoh) said: "Who, then, O Musa, is the Lord of you two?"
He said; "Our Lord is He Who gave to each (created) thing its form and nature, and further, gave (it) guidance."
(Pharaoh) said: "And what was the position of the generations who have passed before?"
Musa (SAW) replied: "The knowledge of that is with my Lord, secure i a writing; My Lord neither errs, nor forgets, "He it is Who has spread as a bed for you, and made paths for you to move about (from place to place); He sent down rain water from the above and produced different kinds of vegetation: eat of these and graze your cattle. Surely there is many a Sign in this for those who possess common sense.
Musa (SAW) showed his signs to impress upon Fir'awn that his message was true. He threw his stick on the ground and it changed into a serpent. Musa (SAW) picked it up and it turned again into a stick. Fir'awn and his followers were amazed to see this. But he thought that Musa (SAW) was a magician and challenged him to face his own magicians who could show even more stunning magic. Sura Ash-Shu'araa (26:23-37)
Pharaoh said: "And what is this Lord of all Creation?'"
Musa (SAW) answered, "The Lord of the heavens and the earth and of all that is between them, if only you care to believe!"
Pharaoh said: To those around him, "Do you hear?"
Musa (SAW) said: "Your Lord as well as Lord of your forefathers who have gone before."
Pharaoh said: (to all those present), "This messenger of yours, who has been sent to you, seems to be utterly mad."
Musa (SAW) said: "(He is) Lord of the east and the west and of all that is between them, if only you people have any common-sense!'"
Pharaoh said: "If you take any one other than me as a deity, I will cast you among those who are rotting in the prisons."
Musa (SAW) said: "Even if I bring forth a convincing thing?"
Pharaoh replied: "Well bring it if you are truthful." (No sooner had he uttered these words than) Musa (SAW) cast down his staff, and suddenly it became a serpent, Then he drew out his hand (from the armpit) and it was shining bright for all the spectators.
Pharaoh said to the chiefs around him, "This fellow is certainly a skilled magician: he wants to drive you out of your land by means of his magic. Now, what is your command?"
They said: "Detain him and his brother for a while, and send forth heralds to the cities to summon every skilled magician into your presence."
