The word(s) "by" appears 593 time(s) in 514 verse(s) in Quran in Abdullah Yusuf Ali translation.

(211) And We made known this decree to him, that the last remnants of those (sinners) should be cut off by the morning.

(213) Behold! in this are Signs for those who by tokens do understand.

(214) Therefore, by the Lord, We will, of a surety, call them to account,

(215) He has made subject to you the Night and the Day; the sun and the moon; and the stars are in subjection by His Command: verily in this are Signs for men who are wise.

(216) And marks and sign-posts; and by the stars (men) guide themselves.

(217) They swear their strongest oaths by Allah, that Allah will not raise up those who die: Nay, but it is a promise (binding) on Him in truth: but most among mankind realise it not.

(218) Or that He may not call them to account by a process of slow wastage - for thy Lord is indeed full of kindness and mercy.

(219) And ye have no good thing but is from Allah: and moreover, when ye are touched by distress, unto Him ye cry with groans;

(220) And they (even) assign, to things they do not know, a portion out of that which We have bestowed for their sustenance! by Allah, ye shall certainly be called to account for your false inventions.
