(125) Say: Allah knows best how long they remained; to Him are (known) the unseen things of the heavens and the earth; how clear His sight and how clear His hearing! There is none to be a guardian for them besides Him, and He does not make any one His associate in His Judgment.

(126) What! do then those who disbelieve think that they can take My servants to be guardians besides Me? Surely We have prepared hell for the entertainment of the unbelievers.

(127) And tenderness from Us and purity, and he was one who guarded (against evil),

(128) She said: Surely I fly for refuge from you to the Beneficent Allah, if you are one guarding (against evil).
