"O my people! Enter the holy land (Palestine) which Allah has assigned to you, and turn not back (in flight) for then you will be returned as losers."
They said:"O Musa (Moses)! In it (this holy land) are a people of great strength, and we shall never enter it, till they leave it; when they leave, then we will enter."
Two men of those who feared (Allah and) on whom Allah had bestowed His Grace [they were Yusha" (Joshua) and Kalab (Caleb)] said:"Assault them through the gate, for when you are in, victory will be yours, and put your trust in Allah if you are believers indeed."
They said:"O Musa (Moses)! We shall never enter it as long as they are there. So go you and your Lord and fight you two, we are sitting right here."
He [Musa (Moses)] said:"O my Lord! I have power only over myself and my brother, so separate us from the people who are the Fasiqun (rebellious and disobedient to Allah)!"
(Allah) said:"Therefore it (this holy land) is forbidden to them for forty years; in distraction they will wander through the land. So be not sorrowful over the people who are the Fasiqun (rebellious and disobedient to Allah)."
And (O Muhammad SAW) recite to them (the Jews) the story of the two sons of Adam [Habil (Abel) and Qabil (Cain)] in truth; when each offered a sacrifice (to Allah), it was accepted from the one but not from the other. The latter said to the former:"I will surely kill you." The former said:"Verily, Allah accepts only from those who are Al-Muttaqun (the pious - see V.2:2)."
"If you do stretch your hand against me to kill me, I shall never stretch my hand against you to kill you, for I fear Allah; the Lord of the"Alamin (mankind, jinns, and all that exists)."
"Verily, I intend to let you draw my sin on yourself as well as yours, then you will be one of the dwellers of the Fire, and that is the recompense of the Zalimun (polytheists and wrong-doers)."
So the Nafs (self) of the other (latter one) encouraged him and made fair-seeming to him the murder of his brother; he murdered him and became one of the losers.
Then Allah sent a crow who scratched the ground to show him to hide the dead body of his brother. He (the murderer) said:"Woe to me! Am I not even able to be as this crow and to hide the dead body of my brother?" Then he became one of those who regretted.
Because of that We ordained for the Children of Israel that if anyone killed a person not in retaliation of murder, or (and) to spread mischief in the land - it would be as if he killed all mankind, and if anyone saved a life, it would be as if he saved the life of all mankind. And indeed, there came to them Our Messengers with clear proofs, evidences, and signs, even then after that many of them continued to exceed the limits (e.g. by doing oppression unjustly and exceeding beyond the limits set by Allah by committing the major sins) in the land!.
The recompense of those who wage war against Allah and His Messenger and do mischief in the land is only that they shall be killed or crucified or their hands and their feet be cut off on the opposite sides, or be exiled from the land. That is their disgrace in this world, and a great torment is theirs in the Hereafter.
Except for those who (having fled away and then) came back (as Muslims) with repentance before they fall into your power; in that case, know that Allah is Oft-Forgiving, Most Merciful.
O you who believe! Do your duty to Allah and fear Him. Seek the means of approach to Him, and strive hard in His Cause as much as you can. So that you may be successful.
Verily, those who disbelieve, if they had all that is in the earth, and as much again therewith to ransom themselves thereby from the torment on the Day of Resurrection, it would never be accepted of them, and theirs would be a painful torment.
They will long to get out of the Fire, but never will they get out therefrom, and theirs will be a lasting torment.
Cut off (from the wrist joint) the (right) hand of the thief, male or female, as a recompense for that which they committed, a punishment by way of example from Allah. And Allah is All-Powerful, All-Wise.
But whosoever repents after his crime and does righteous good deeds (by obeying Allah), then verily, Allah will pardon him (accept his repentance). Verily, Allah is Oft-Forgiving, Most Merciful.
Know you not that to Allah (Alone) belongs the dominion of the heavens and the earth! He punishes whom He wills and He forgives whom He wills. And Allah is Able to do all things.
