The word(s) "rein" appears 361 time(s) in 325 verse(s) in Quran in Muhammad Pickthal translation.

(251) He placed therein firm hills rising above it, and blessed it and measured therein its sustenance in four Days, alike for (all) who ask;

(252) That is the reward of Allah's enemies: the Fire. Therein is their immortal home, payment forasmuch as they denied Our revelations.

(253) And in whatsoever ye differ, the verdict therein belongeth to Allah. Such is my Lord, in Whom I put my trust, and unto Whom I turn.

(254) He hath ordained for you that religion which He commended unto Noah, and that which We inspire in thee (Muhammad), and that which We commended unto Abraham and Moses and Jesus, saying: Establish the religion, and be not divided therein. Dreadful for the idolaters is that unto which thou callest them. Allah chooseth for Himself whom He will, and guideth unto Himself him who turneth (toward Him).

(255) Those who believe not therein seek to hasten it, while those who believe are fearful of it and know that it is the Truth. Are not they who dispute, in doubt concerning the Hour, far astray?

(256) And of His portents is the creation of the heaven and the earth, and of whatever beasts He hath dispersed therein. And He is Able to gather them when He will.

(257) If He will He calmeth the wind so that they keep still upon its surface - Lo! herein verily are signs for every steadfast grateful (heart). -

(258) Who made the earth a resting-place for you, and placed roads for you therein, that haply ye may find your way;

(259) And now that the Truth hath come unto them they say: This is mere magic, and lo! we are disbelievers therein.

(260) Therein are brought round for them trays of gold and goblets, and therein is all that souls desire and eyes find sweet. And ye are immortal therein.
