The word(s) "obscure" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) He said: "O my people! See ye if (it be that) I have a Clear Sign from my Lord, and that He hath sent Mercy unto me from His own presence, but that the Mercy hath been obscured from your sight? shall we compel you to accept it when ye are averse to it?

(2) We have made the Night and the Day as two (of Our) Signs: the Sign of the Night have We obscured, while the Sign of the Day We have made to enlighten you; that ye may seek bounty from your Lord, and that ye may know the number and count of the years: all things have We explained in detail.

(3) Then the (whole) story that Day will seem obscure to them (like light to the blind) and they will not be able (even) to question each other.
