The word(s) "clot" appears 20 time(s) in 16 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) O you who believe! let those whom your right hands possess and those of you who have not attained to puberty ask permission of you three times; before the morning prayer, and when you put off your clothes at midday in summer, and after the prayer of the nightfall; these are three times of privacy for you; neither is it a sin for you nor for them besides these, some of you must go round about (waiting) upon others; thus does Allah make clear to you the communications, and Allah is Knowing, Wise.

(12) And (as for) women advanced in years who do not hope for a marriage, it is no sin for them if they put off their clothes without displaying their ornaments; and if they restrain themselves it is better for them; and Allah is Hearing, Knowing.

(13) He it is Who created you from dust, then from a small lifegerm, then from a clot, then He brings you forth as a child, then that you may attain your maturity, then that you may be old-- and of you there are some who are caused to die before-- and that you may reach an appointed term, and that you may understand.

(14) O you who are clothed!

(15) Then he was a clot of blood, so He created (him) then made (him) perfect.

(16) He created man from a clot.
