It is to be noted that the father of the two girls was the famous prophet Hazrat Shuaib A. who was sent to the people of Midian. Musa A. had never heard his name or known him before. Moses narrated to him everything that had happened to him. Shu'aib heard everything and said, "Do not be afraid, you have been freed from the wrongdoing people." At that time one of the two girls said, father! Leave it at home as an employee. Because he will be better as a helper of your actions, who will be strong and faithful. (Near Surah)
Then he looked at Musa and said, "I want to marry one of my two daughters to you on the condition that you stay in my house as an employee for eight years." But if you complete ten years, that is your wish. God willing, he will find me righteous. Musa (AS) said, "It has been agreed between you and me that if you fulfill one of the two terms, there will be no charge against me." GOD is Seer of what we say.
Basically this was the seal of their marriage. Earlier, Yakub A. had raised sheep at his father-in-law's house for seven years for his wife's dowry. Ibn 'Abbas said that he had completed the compulsory eight-year term of service and the optional two-year term. (Sahih Bukhari, Ha-246)
Journey to Egypt-
Mohrana’s contract expired, in ten years she had two sons and left her father-in-law for Egypt with a flock of sheep and family. On the way to Mount Sinai, on the border of Egypt, near the mountain of Malar Tur, when his wife's labor pains suddenly began, he lost his way in need of fire and looked around. Suddenly he saw a light of fire in the distance and said to his wife and family, "Stay here, I have seen fire, I will bring some fire from it for you and find the way." (Surat at-Tawaha: 10)
Moses, following the advice of his father-in-law, left the familiar road and followed the unfamiliar road, lost his way in the desert and reached the western edge of Mount Tur. Originally, Path Harunota was part of God's grand plan.
The more hopeful Moses is to go to the fire, the more the light of the fire stays behind. He was amazed to see that the fire was burning on the green tree but the leaves were not burning, but its brightness was increasing. Overwhelmed with amazement, Musa A. stared at the fire. Suddenly a solemn voice came to my ears. Musa A. was standing in the valley of Tuba on the right side of Mount Tur.
Allaah says (interpretation of the meaning): “And when he reached the Fire, a voice came to him saying: O Musa! I am your Lord. So take off your shoes. You are in the holy valley of Tuba. ' (Surah Tawaha - 11/12)
Allaah says (interpretation of the meaning): And I have chosen you. So listen carefully to what is being revealed to you. Surely I am Allah. There is no deity except Me, so worship Me and establish prayer in My remembrance. The Hour is sure to come. Let him not restrain you. Then you will be destroyed. ' (Surah Tawaha - 13/18)
