Say to My believing servants, "Have fear of your Lord. Those who act righteously in this life will receive good reward. The land of God is vast. God will recompense the deeds of those who have exercised patience, without keeping an account". 10 Say, [O Muhammad], "Indeed, I have been commanded to worship Allah, [being] sincere to Him in religion. 11 and I am bidden to be foremost among those who surrender themselves unto God." 12 Say: 'Truly I fear, if I should rebel against my Lord, the chastisement of a dreadful day.' 13 Say: Allah I worship, making my religion pure for Him (only). 14 So serve, apart from Him, whomsoever you please.” Say: “Behold, the real losers shall be those who will have lost their own selves and their kith and kin on the Day of Resurrection. Behold, that is the obvious loss. 15 They shall have coverings of Fire, above them and covering (of Fire) beneath them; with this Allah does frighten His slaves: "O My slaves, therefore fear Me!" 16 seeing that for those who shun the powers of evil lest they [be tempted to] worship them, and turn unto God instead, there is the glad tiding [of happiness in the life to come]. Give, then, this glad tiding to [those of] My servants 17 Who hear advice and follow the best thereof. Such are those whom Allah guideth, and such are men of understanding. 18 On the other hand, could one on whom [God's] sentence of suffering has been passed [be rescued by man]? Couldst thou, perchance, save one who is [already, as it were,] in the fire? 19 As against this they who of their Sustainer are conscious shall [in the life to come] have mansions raised upon mansions high, beneath which running waters flow: [this is] God's promise - [and] never does God fail to fulfill His promise. 20 Hast thou not seen how Allah hath sent down water from the sky and hath caused it to penetrate the earth as watersprings, and afterward thereby produceth crops of divers hues; and afterward they wither and thou seest them turn yellow; then He maketh them chaff. Lo! herein verily is a reminder for men of understanding. 21
