The word(s) "reckon" appears 42 time(s) in 42 verse(s) in Quran in Muhammad Pickthal translation.

(21) Their reckoning draweth nigh for mankind, while they turn away in heedlessness.

(22) And We set a just balance for the Day of Resurrection so that no soul is wronged in aught. Though it be of the weight of a grain of mustard seed, We bring it. And We suffice for reckoners.

(23) And they will bid thee hasten on the Doom, and Allah faileth not His promise, but lo! a Day with Allah is as a thousand years of what ye reckon.

(24) He who crieth unto any other god along with Allah hath no proof thereof. His reckoning is only with his Lord. Lo! disbelievers will not be successful.

(25) As for those who disbelieve, their deeds are as a mirage in a desert. The thirsty one supposeth it to be water till he cometh unto it and findeth it naught, and findeth, in the place thereof, Allah Who payeth him his due; and Allah is swift at reckoning.

(26) Lo! their reckoning is my Lord's concern, if ye but knew;

(27) Whoso looketh forward to the meeting with Allah (let him know that) Allah's reckoning is surely nigh, and He is the Hearer, the Knower.

(28) He directeth the ordinance from the heaven unto the earth; then it ascendeth unto Him in a Day, whereof the measure is a thousand years of that ye reckon.

(29) O ye who believe! If ye wed believing women and divorce them before ye have touched them, then there is no period that ye should reckon. But content them and release them handsomely.

(30) They say: Our Lord! Hasten on for us our fate before the Day of reckoning.
