(61) But the misbelievers say: "Naught is this but a lie which he has forged, and others have helped him at it." In truth it is they who have put forward an iniquity and a falsehood.

(62) Those who witness no falsehood, and, if they pass by futility, they pass by it with honourable (avoidance);

(63) He said: "O my Lord! I do fear that they will charge me with falsehood:

(64) Then Moses threw his rod, when, behold, it straightway swallows up all the falsehoods which they fake!

(65) Say: Praise be to Allah, and Peace on his servants whom He has chosen (for his Message). (Who) is better?- Allah or the false gods they associate (with Him)?

(66) "And my brother Aaron - He is more eloquent in speech than I: so send him with me as a helper, to confirm (and strengthen) me: for I fear that they may accuse me of falsehood."

(67) We did test those before them, and Allah will certainly know those who are true from those who are false.

(68) They will bear their own burdens, and (other) burdens along with their own, and on the Day of Judgments they will be called to account for their falsehoods.

(69) "For ye do worship idols besides Allah, and ye invent falsehood. The things that ye worship besides Allah have no power to give you sustenance: then seek ye sustenance from Allah, serve Him, and be grateful to Him: to Him will be your return.

(70) And those who have rejected Faith and falsely denied our Signs and the meeting of the Hereafter,- such shall be brought forth to Punishment.
