The word(s) "nature" appears 33 time(s) in 32 verse(s) in Quran in Muhammad Pickthal translation.

(12) We sent not before thee (any messengers) save men whom We inspired from among the folk of the townships - Have they not travelled in the land and seen the nature of the consequence for those who were before them? And verily the abode of the Hereafter, for those who ward off (evil), is best. Have ye then no sense? -

(13) And verily We have raised in every nation a messenger, (proclaiming): Serve Allah and shun false gods. Then some of them (there were) whom Allah guided, and some of them (there were) upon whom error had just hold. Do but travel in the land and see the nature of the consequence for the deniers!

(14) Lo! Abraham was a nation obedient to Allah, by nature upright, and he was not of the idolaters;

(15) And afterward We inspired thee (Muhammad, saying): Follow the religion of Abraham, as one by nature upright. He was not of the idolaters.

(16) He said: Our Lord is He Who gave unto everything its nature, then guided it aright.

(17) And they denied them, though their souls acknowledged them, for spite and arrogance. Then see the nature of the consequence for the wrong-doers!

(18) Then see the nature of the consequence of their plotting, for lo! We destroyed them and their people, every one.

(19) Say (unto them, O Muhammad): Travel in the land and see the nature of the sequel for the guilty!

(20) Therefor We seized him and his hosts, and abandoned them unto the sea. Behold the nature of the consequence for evil-doers!
