Je was op zoek naar: mtikiso (Swahili - Engels)

itakapo tikiswa ardhi kwa mtikiso,
this will happen when the earth is shaken, shaken

siku zitakapo tikisika mbingu kwa mtikiso,
(it shall come to pass) on the day when the heaven will convulse in a great convulsion,

hapo ndipo waumini walipo jaribiwa, na wakatikiswa mtikiso mkali.
in that situation were the believers tried: they were shaken as by a tremendous shaking.

lakini walimkanusha basi ukawatwaa mtikiso wa ardhi, wakapambazukiwa ndani ya nyumba zao nao wamefudikia.
and they belied him [shu'aib (shuaib)], so the earthquake seized them, and they lay (dead), prostrate in their dwellings.
