The word(s) "left" appears 54 time(s) in 51 verse(s) in Quran in Muhammad Pickthal translation.

(31) Have they not travelled in the land to see the nature of the consequence for those who disbelieved before them? They were mightier than these in power and (in the) traces (which they left behind them) in the earth. Yet Allah seized them for their sins, and they had no protector from Allah.

(32) Have they not travelled in the land to see the nature of the consequence for those before them? They were more numerous than these, and mightier in power and (in the) traces (which they left behind them) in the earth. But all that they used to earn availed them not.

(33) How many were the gardens and the watersprings that they left behind,

(34) Those of the wandering Arabs who were left behind will tell thee: Our possessions and our households occupied us, so ask forgiveness for us! They speak with their tongues that which is not in their hearts. Say: Who can avail you aught against Allah, if He intend you hurt or intend you profit? Nay, but Allah is ever Aware of what ye do.

(35) Those who were left behind will say, when ye set forth to capture booty: Let us go with you. They fain would change the verdict of Allah. Say (unto them, O Muhammad): Ye shall not go with us. Thus hath Allah said beforehand. Then they will say: Ye are envious of us. Nay, but they understand not, save a little.

(36) Say unto those of the wandering Arabs who were left behind: Ye will be called against a folk of mighty prowess, to fight them until they surrender; and if ye obey, Allah will give you a fair reward; but if ye turn away as ye did turn away before, He will punish you with a painful doom.

(37) When the two Receivers receive (him), seated on the right hand and on the left,

(38) And We left behind therein a portent for those who fear a painful doom.

(39) And verily We left it as a token; but is there any that remembereth?

(40) And (then) those on the left hand; what of those on the left hand?
