The general concept of Taqwa is fear of Allah. But to be more precise Taqwa comes in loving Allah more than anything else and fearing to displease Allah by doing things prohibited by Him. Together with our fear of Allah we should also have hope of His Mercy
Iqlas is the sincerity in all our actions. Our Ibadaa and deeds should not be for show off or fearing some one else
Only when we do Ibadaa and deeds with Taqwa and Iqlas it will be accepted by Allah
