And know that Allah is with the righteous. 123 Whenever a chapter is sent down to you, some ask: 'Which of you has it increased in belief' It will surely increase the belief of the believers and they are joyful. 124 But as for those in whose hearts is a disease (of doubt, disbelief and hypocrisy), it will add suspicion and doubt to their suspicion, disbelief and doubt, and they die while they are disbelievers. 125 Are they, then, not aware that they are being tested year-in, year-out? And yet, they do not repent and do not bethink themselves [of God]; 126 And whenever a chapter is revealed, they cast glances at one another: Does any one see you?
