The word(s) "sever" appears 30 time(s) in 29 verse(s) in Quran in Muhammad Pickthal translation.

(21) Who persevere, and put their trust in their Lord!

(22) O my dear son! Establish worship and enjoin kindness and forbid iniquity, and persevere whatever may befall thee. Lo! that is of the steadfast heart of things.

(23) Lo! men who surrender unto Allah, and women who surrender, and men who believe and women who believe, and men who obey and women who obey, and men who speak the truth and women who speak the truth, and men who persevere (in righteousness) and women who persevere, and men who are humble and women who are humble, and men who give alms and women who give alms, and men who fast and women who fast, and men who guard their modesty and women who guard (their modesty), and men who remember Allah much and women who remember - Allah hath prepared for them forgiveness and a vast reward.

(24) Allah coineth a similitude: A man in relation to whom are several part-owners, quarrelling, and a man belonging wholly to one man. Are the two equal in similitude? Praise be to Allah! But most of them know not.

(25) That was because their messengers kept bringing them clear proofs (of Allah's Sovereignty) but they disbelieved; so Allah seized them. Lo! He is Strong, severe in punishment.

(26) Would ye then, if ye were given the command, work corruption in the land and sever your ties of kinship?

(27) O ye who believe! Ward off from yourselves and your families a Fire whereof the fuel is men and stones, over which are set angels strong, severe, who resist not Allah in that which He commandeth them, but do that which they are commanded.

(28) And then severed his life-artery,

(29) And to be of those who believe and exhort one another to perseverance and exhort one another to pity.
