Commentary
وَلُوطًا إِذْ قَالَ لِقَوْمِهِ إِنَّكُمْ لَتَأْتُونَ الْفَاحِشَةَ (And [ We sent ] Sayyidna Lut (علیہ السلام) when he said to his people, "Indeed you commit the shameful act - 29:28). Here Sayyidna Lut (علیہ السلام) has described three vicious sins of his people. One, unnatural offence of man with man; two, highway robbery against travelers; and three, commitment of sin openly before others in their group meetings. There is no specification of the third sin in the Holy Qur'an. Thus, it is deduced that every sin, which is a sin in its own right, if committed openly with indifference, it becomes a double sin, irrespective of the type of sin. At this point, some Imams of Tafsir (exegesis) have listed all such sins, which these wretched persons used to commit in their meetings. For instance, throwing stones on travelers and making fun of them, as Umm Hani' ؓ reports it in a hadith. Other commentators have reported that these insolent people were in the habit of committing sins openly before all others.
Out of the three sins mentioned in this verse the first one is most disgusting, which was never committed before in the whole world, and even wild beasts abstain from it. The entire ummah is unanimous on that it is a worse sin than adultery. (Ruh)
