The word(s) "understand" appears 86 time(s) in 86 verse(s) in Quran in Muhammad Habib Shakir translation.

(41) Is he then who knows that what has been revealed to you from your Lord is the truth like him who is blind? Only those possessed of understanding will mind,

(42) This is a sufficient exposition for the people and that they may be warned thereby, and that they may know that He is One Allah and that those possessed of understanding may mind.

(43) The seven heavens declare His glory and the earth (too), and those who are in them; and there is not a single thing but glorifies Him with His praise, but you do not understand their glorification; surely He is Forbearing, Forgiving.

(44) And We have placed coverings on their hearts and a heaviness in their ears lest they understand it, and when you mention your Lord alone in the Quran they turn their backs in aversion.

(45) And who is more unjust than he who is reminded of the communications of his Lord, then he turns away from them and forgets what his two hands have sent before? Surely We have placed veils over their hearts lest they should understand it and a heaviness in their ears; and if you call them to the guidance, they will not ever follow the right course in that case.

(46) Until when he reached (a place) between the two mountains, he found on that side of them a people who could hardly understand a word.

(47) (That) they may understand my word;

(48) Eat and pasture your cattle; most surely there are signs in this for those endowed with understanding.

(49) Does it not then direct them aright how many of the generations In whose dwelling-places they go about We destroyed before them? Most surely there are signs in this for those endowed with understanding.

(50) Certainly We have revealed to you a Book in which is your good remembrance; what! do you not then understand?
