Amatul Rahmân Omer:
And (Prophet! recall the time) when We said to you, `Surely, your Lord has encompassed all people (for destruction) and has power over them (still they remained indifferent).´ We made the vision which We showed you (being carried to Jerusalem from Makkah by night) and also the tree (- evil word; see 14:26) disapproved of in the Qur´ân, a means of distinction between the good and the bad for the people. (Despite the fact that) We have been warning them (by sending Our signs), this (warning from Us) only leads them to unrestrained inordinacy.
