The facts prove that no god called Allah and no angel called Jibril (Gabriel) could have ever revealed anything so contorted and convoluted to Muhammad.
Although we have already conclusively demonstrated that every letter, word, verse/ ayah and chapter/ surah in the Quran are the product of Muhammad’s imagination and or the secretions of Muhammad’s warped mind, we shall none the less continue incessantly to reveal more and more of his depravities and obscene degrees of deception so that there will never be any doubt that Muhammad was the most successful charlatan that was ever able to successfully and continually deceive hundreds of millions of human beings in recorded history.
As usual, we shall prove our points based entirely on Muhammad’s Quran and Islamic scripture (the complete verses are in Muhammad’s Quran).
Al Baqara 2: 246  “Hast thou not turned thy vision to the chiefs of the children of Israel after (the time of) Moses?  They said to a Prophet [Samuel] (that was) among them: “Appoint for us a king that we may fight in the cause of Allah. …”
247  “And their prophet said to them, “Indeed, Allah has sent to you Talut as a king.” They said, “How can he have kingship over us while we are more worthy of kingship than him and he has not been given any measure of wealth?” He said, “Indeed, Allah has chosen him over you and has increased him abundantly in knowledge and stature. And Allah gives His sovereignty to whom He wills. And Allah is all-Encompassing [in favour] and Knowing…..”
Al Baqara 2:248 “And their prophet said to them ‘A sign of his authority is that there shall come to you the Ark of the Covenant…”
*** The Sacred Ark was returned to Israel before Saul’s accession***
249  When Talut [Saul] set forth with the armies he said: “Allah will test you at the stream; if any drinks of its water he goes not with my army; only those who taste not of it go with me; a mere sip out of the hand is excused.” …. “But they all drank of it except a few. When they crossed the river he and the faithful ones with him they said: “This day we cannot cope with Jalut (Goliath) and his forces.” 
250  When they advanced to meet Jalut (Goliath) and his forces they prayed: “Our Lord! pour out constancy on us and make our steps firm; help us against those that reject faith.”
251  By Allah’s will they routed them: and David slew Jalut (Goliath); and Allah gave him power and wisdom and taught him whatever (else) He willed…”
These verses describe the Biblical David and Goliath encounter. Allah or Muhammad yet again got their information in a twist confusing the Stories of Gideon and Saul with that of David and Goliath.
The Muslim exegetes explain the above verse as follows~
The Israelites demanded a King after the time of Musa (Moses), to lead them into war against their foes. Talut (Saul) was chosen by the prophet of Israel (the name of Samuel is not mentioned explicitly, but rather as “a prophet” of the Israelites). The  prophet announced that Allah chose Talut as their King.
The Israelites questioned Samuel about this, lacking respect for Talut as he was not wealthy. Samuel then told them that Talut was more favoured than they were. He was distinguished by the greatness of his knowledge and of his physique. A sign of his role as King was that Allah brought back the Ark of the Covenant for Israel.
Talut tested his people at a river; whoever drank from it would not follow him in battle excepting one who took from it in “the hollow of the hand.” Many drank, and only the faithful ventured on. Talut led the Israelites to victory over the army of Goliath, who was killed by Dawud (David).
The Quranic account differs enormously from the Biblical account (if Talut = Saul; Jalut = Goliath and if Allah = God) because in the Bible~
Judges 7: 3 “Now announce to the army, ‘Anyone who trembles with fear may turn back and leave Mount Gilead.’ ” So twenty-two thousand men left, while ten thousand remained. 4 But the LORD said to Gideon, “There are still too many men. Take them down to the water, and I will thin them out for you there. If I say, ‘This one shall go with you,’ he shall go; but if I say, ‘This one shall not go with you,’ he shall not go.” 5 So Gideon took the men down to the water. There the LORD told him, “Separate those who lap the water with their tongues as a dog laps from those who kneel down to drink.” 6 Three hundred of them drank from cupped hands, lapping like dogs. All the rest got down on their knees to drink. 7 The LORD said to Gideon, “With the three hundred men that lapped I will save you and give the Midianites into your hands. Let all the others go home.” 8 So Gideon sent the rest of the Israelites home but kept the three hundred, who took over the provisions and trumpets of the others. Now the camp of Midian lay below him in the valley”
