Quranic Verses on Free Will and Determinism:  (Pickthall, transl)

 
 
  2.6 As for the Disbelievers, Whether thou warn them or thou warn them not it is all one for them; they believe not. 7 Allah hath sealed their hearing and their hearts, and on their eyes there is a covering. Theirs will be an awful doom. 2.8 And of mankind are some who say: We believe in Allah and the Last Day, when they believe not. 2.9 They think to beguile Allah and those who believe, and they beguile none save themselves; but they perceive not. 2.10 In their hearts is a disease, and Allah increaseth their disease. A painful doom is theirs because they lie. 

2:26 … then as for those who believe, they know that it is the truth from their Lord, and as for those who disbelieve, they say: What is it that Allah means by this parable: He causes many to err by it and many He leads aright by it! but He does not cause to err by it (any) except the transgressors, 

2:142 The foolish of the people will say: What hath turned them from the qiblah which they formerly observed? Say: Unto Allah belong the East and the West. He guideth whom He will unto a straight path.

2:264 O ye who believe! Render not vain your almsgiving by reproach and injury, like him who spendeth his wealth only to be seen of men and believeth not in Allah and the Last Day. His likeness is as the likeness of a rock whereon is dust of earth; a rainstorm smiteth it, leaving it smooth and bare. They have no control of aught of that which they have gained. Allah guideth not the disbelieving folk.

3:86 How shall Allah guide a people who disbelieved after their belief and (after) they bore witness that the messenger is true and after clear proofs (of Allah's Sovereignty) had come unto them. And Allah guideth not wrongdoing folk.

4:88 What aileth you that ye are become two parties regarding the hypocrites, when Allah cast them back (to disbelief) because of what they earned? Seek ye to guide him whom Allah hath sent astray? He whom Allah sendeth astray, for him thou (O Muhammad) canst not find a road.

4:115 And whoso opposeth the messenger after the guidance (of Allah) hath been manifested unto him, and followeth other than the believer's way, We appoint for him that unto which he himself hath turned, and expose him unto hell - a hapless journey's end!

5:15-16 O People of the Scripture! Now hath Our messenger come unto you, expounding unto you much of that which ye used to hide in the Scripture, and forgiving much. now hath come unto you light from Allah and plain Scripture,  16 Whereby Allah guideth him who seeketh His good pleasure unto paths of peace. He bringeth them out of darkness unto light by His decree, and guideth them unto a straight path

6:82-88: Those who believe and obscure not their belief by wrongdoing, theirs is safety; and they are rightly guided. 6.83 That is Our argument. We gave it unto Abraham against his folk. We raise unto degrees of wisdom whom We will. Lo! thy Lord is Wise, Aware. 6.84 And We bestowed upon him Isaac and Jacob; each of them We guided; and Noah did We guide aforetime; and of his seed (We guided) David and Solomon and Job and Joseph and Moses and Aaron. Thus do We reward the good. 6.85 And Zachariah and John and Jesus and Elias. Each one (of them) was of the righteous. 6.86 And Ishmael and Elisha and Jonah and Lot. Each one (of them) did We prefer above (Our) creatures, 6.87 With some of their forefathers and their offspring and their brethren; and We chose them and guided them unto a straight path. 6.88 Such is the guidance of Allah wherewith He guideth whom He will of His bondmen. But if they had set up (for worship) aught beside Him, (all) that they did would have been vain. 
 

6.108 Revile not those unto whom they pray beside Allah lest they wrongfully revile Allah through ignorance. Thus unto every nation have We made their deed seem fair. Then unto their Lord is their return, and He will tell them what they used to do. 109 And they swear a solemn oath by Allah that if there come unto them a portent they will believe therein. Say; Portents are with Allah and (so is) that which telleth you that if such came unto them they would not believe. 110 We confound their hearts and their eyes. As they believed not therein at the first, We let them wander blindly on in their contumacy. 
111  And though We should send down the angels unto them, and the dead should speak unto them, and We should gather against them all things in array, they would not believe unless Allah so willed. Howbeit, most of them are ignorant. 

7:178 He whom Allah leadeth, he indeed is led aright, while he whom Allah sendeth astray - they indeed are losers.

8.52 (Their way is) as the way of Pharaoh's folk and those before them; they disbelieved the revelations of Allah, and Allah took them in their sins. Lo! Allah is Strong, severe in punishment. 8.053 That is because Allah never changeth the grace He hath bestowed on any people until they first change that which is in their hearts, and (that is) because Allah is Hearer, Knower. 

9.78 Know they not that Allah knoweth both their secret and the thought that they confide, and that Allah is the Knower of Things Hidden? 
9.79 Those who point at such of the believers as give the alms willingly and such as can find naught to give but their endeavours, and deride them - Allah (Himself) derideth them. Theirs will be a painful doom. 9.80 Ask forgiveness for them (O Muhammad), or ask not forgiveness for them; though thou ask forgiveness for them seventy times Allah will not forgive them. That is because they disbelieved in Allah and His messenger, and Allah guideth not wrongdoing folk. 

10.99  And if thy Lord willed, all who are in the earth would have believed together. Wouldst thou (Muhammad) compel men until they are believers? 100 It is not for any soul to believe save by the permission of Allah. He hath set uncleanness upon those who have no sense. 

13:11 For him are angels ranged before him and behind him, who guard him by Allah's command. Lo!

14:4 And We never sent a messenger save with the language of his folk, that he might make (the message) clear for them. Then Allah sendeth whom He will astray, and guideth whom He will. He is the Mighty, the Wise.

17:16 And when We would destroy a township We send commandment to its folk who live at ease, and afterward they commit abomination therein, and so the Word (of doom) hath effect for it, and we annihilate it with complete annihilation.

76:29  Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 30 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise.
