(124) But they did ham-string her. So he said: "Enjoy yourselves in your homes for three days: (Then will be your ruin): (Behold) there a promise not to be belied!"

(126) When Our messengers came to Lut, he was grieved on their account and felt himself powerless (to protect) them. He said: "This is a distressful day."

(127) To the Madyan People (We sent) Shu'aib, one of their own brethren: he said: "O my people! worship Allah: Ye have no other god but Him. And give not short measure or weight: I see you in prosperity, but I fear for you the penalty of a day that will compass (you) all round.

(128) He will go before his people on the day of Judgment, and lead them into the Fire (as cattle are led to water): But woeful indeed will be the place to which they are led!

(130) In that is a Sign for those who fear the penalty of the Hereafter: that is a day for which mankind will be gathered together: that will be a day of Testimony.
