Translation:

54. And (then unbelievers) plotted and planned and Allah too planned and the best of planners is Allah.

Notes (Tafseer)

393. The Arabic Makara has both a bad and a good meaning, that of making an intricate plan to carry out some secret purpose. The enemies of Allah are constantly doing that. But Allah-in whose hands is all good-has His plans also, against which the evil ones will have no chance whatever.
