The word(s) "limits" appears 42 time(s) in 35 verse(s) in Quran in Muhammad Habib Shakir translation.

(31) But whoever has not the means, let him fast for two months successively before they touch each other; then as for him who is not able, let him feed sixty needy ones; that is in order that you may have faith in Allah and His Apostle, and these are Allah's limits, and the unbelievers shall have a painful punishment.

(32) O Prophet! when you divorce women, divorce them for~ their prescribed time, and calculate the number of the days prescribed, and be careful of (your duty to) Allah, your Lord. Do not drive them out of their houses, nor should they themselves go forth, unless they commit an open indecency; and these are the limits of Allah, and whoever goes beyond the limits of Allah, he indeed does injustice to his own soul. You do not know that Allah may after that bring about reunion.

(33) Forbidder of good, outstepping the limits, sinful,

(34) But he who seeks to go beyond this, these it is that go beyond the limits--

(35) And none gives the lie to it but every exceeder of limits, sinful one
