The word(s) "speck" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) Or have they a share in the dominion? Then in that case they would not give mankind even a speck on the back of a date-stone.

(2) And whoever does righteous good deeds, male or female, and is a (true) believer [in the Oneness of Allah (Muslim)], such will enter Paradise and not the least injustice, even to the size of a speck on the back of a date-stone, will be done to them.
