(Lut) said:"Verily, these are my guests, so do not shame me. And have Taqwa of Allah, and do not disgrace me."This is what Lut said to them before he knew that his guests were messengers from Allah, as mentioned in Surah Hud, but here (in this Surah), we have already been told that they are messengers from Allah, and this is followed by an account of Lut's people coming and his exchange with them.However, here the conjunction (wa, meaning "and") does not imply the sequence of events, especially since there is something to indicate that this is not the case.They said answering him,قَالُوا أَوَلَمْ نَنْهَكَ عَنِ الْعَالَمِينَ
