The word(s) "straiten" appears 21 time(s) in 21 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) And by breast straitens, and my tongue is not eloquent, therefore send Thou to Haroun (to help me);

(12) And those who yearned for his place only the day before began to say: Ah! (know) that Allah amplifies and straitens the means of subsistence for whom He pleases of His servants; had not Allah been gracious to us, He would most surely have abased us; ah! (know) that the ungrateful are never successful.

(13) Allah makes abundant the means of subsistence for whom He pleases of His servants, and straitens them for whom (He pleases) surely Allah is Cognizant of all things.

(14) Do they not see that Allah makes ample provision for whom He pleases, or straitens? Most surely there are signs in this for a people who believe.

(15) Say: Surely my Lord amplifies the means of subsistence for whom He pleases and straitens (for whom He pleases), but most men do not know.

(16) Say: Surely my Lord amplifies the means of subsistence for whom He pleases of His servants and straitens (them) for whom (He pleases), and whatever thing you spend, He exceeds it in reward, and He is the best of Sustainers.

(17) Do they not know that Allah makes ample the means of subsistence to whom He pleases, and He straitens; most surely there are signs in this for a people who believe.

(18) His are the treasures of the heavens and the earth; He makes ample and straitens the means of subsistence for whom He pleases; surely He is Cognizant of all things.

(19) Lodge them where you lodge according to your means, and do not injure them in order that you may straiten them; and if they are pregnant, spend on them until they lay down their burden; then if they suckle for you, give them their recompense and enjoin one another among you to do good; and if you disagree, another (woman) shall suckle for him.

(20) Let him who has abundance spend out of his abundance and whoever has his means of subsistence straitened to him, let him spend out of that which Allah has given him; Allah does not lay on any soul a burden except to the extent to which He has granted it; Allah brings about ease after difficulty.
