The followers of Musa NabiAS were liberated from the tyranny of the Pharaoh because they remained steadfast to Musa NabiAS. They crossed the sea with him, while the Pharaoh and his army drowned.
It is said that the day Allah saved Musa NabiAS and his followers from the Pharaoh was the day of Ashura. Thenceforth, the Jews honoured this day by observing a fast.
By the grace of Allah, the followers of Musa NabiAS inherited the wealth and the worth of the Pharaoh. As Allah states,
“And We made a people, considered weak (and of no account), inheritors of lands in both East and West– lands whereon We sent down Our blessings. The fair promise of thy Lord was fulfilled for the Children of Israel, because they had patience and constancy, and We levelled to the ground the great works and fine buildings which Pharaoh and his people erected (with such pride).” (Qur’an, 7:137)
Musa NabiAS led his followers out of Egypt to their homeland Jerusalem. On their way, they came across people who did not believe in one creator and worshipped several deities. Seeing them, a few ignorant individuals insisted upon having some deities. They said,
“O Moses! Fashion for us a god like unto the gods they have.” (Qur’an, 7:138)
Musa NabiAS reprimanded them saying,
“Surely ye are a people without knowledge.” (Qur’an, 7:138)
The journey to Jerusalem was long and tiring. Stores of food and water they had carried while departing from Egypt depleted day by day. Finally, they were left with no water. Musa NabiAS prayed to Allah to give water to his followers, upon which, he was granted his famous miracle of the twelve springs. Replying to his prayers, Allah said,
“Strike the rock with thy staff.” Then gushed forth therefrom twelve springs. Each group knew its own place for water.” (Qur’an, 2:60)
Each day, Allah gifted the followers of Musa NabiAS an unprecedented blessing. He did not asked them for any favour in return but to remain steadfast to the teachings of their Nabi .
However, the followers of Musa NabiAS kept asking for favour after favour, while their faith and belief grew weaker. Having faced the tyranny of the Pharaohs for years, they should have valued the liberty gained at the hands of Musa NabiAS. But, they were ungrateful. Their demands were unending as was their disobedience towards Allah and His Nabi.
Eventually, they asked Musa NabiAS,
“O Moses! We cannot endure one kind of food (always); so beseech thy Lord for us to produce for us of what the earth groweth, -its pot-herbs, and cucumbers, its garlic, lentils, and onions.” (Qur’an, 2:61)
Musa NabiAS reminded them of the bounties they were receiving being with him but they were more inclined towards cheaper and lower fortunes. Finally he said,
“Will ye exchange the better for the worse? Go ye down to any town, and ye shall find what ye want!” (Qur’an, 2:61)
They were filled with humiliation and misery. They drew on themselves the wrath of Allah. This because they went on rejecting the Signs of Allah, rebelled and slayed His messenger without just cause.
