The word(s) "mud" appears 34 time(s) in 33 verse(s) in Quran in Mohsin Khan translation.

(21) "Like the fate of the people of Nuh (Noah), and 'Ad, and Thamud and those who came after them. And Allah wills no injustice for (His) slaves.

(22) But if they turn away, then say (O Muhammad صلى الله عليه وسلم): "I have warned you of a Sa'iqah (a destructive awful cry, torment, hit, a thunderbolt) like the Sa'iqah which overtook 'Ad and Thamud (people)."

(23) And as for Thamud, We showed and made clear to them the Path of Truth (Islamic Monotheism) through Our Messenger, (i.e. showed them the way of success), but they preferred blindness to guidance; so the Sa'iqah (a destructive awful cry, torment, hit, a thunderbolt) of disgracing torment seized them because of what they used to earn.

(24) Denied before them (i.e. these pagans of Makkah) the people of Nuh (Noah), and the dwellers of Rass, and Thamud;

(25) And in Thamud (there is also a sign), when they were told: "Enjoy yourselves for a while!"

(26) And Thamud (people): He spared none of them.

(27) Thamud (people also) belied the warnings.

(28) Thamud and 'Ad people denied the Qari'ah (the striking Hour of Judgement)!

(29) As for Thamud, they were destroyed by the awful cry!

(30) While He has created you in (different) stages [i.e. first Nutfah, then 'Alaqah and then mudghah, see (V.23:13,14)].
