It is narrated from Hasan regarding the Divine command {إنَّ جَہَنَّمَ کَانَتْ مِرْصَادًا }. He says: By God! Hell will lie in wait for the criminals. It is said that during this time, a man will be passing by when another man will come before him and say to him: Have you heard that there is an ambush on the way? He will reply: Yes. The first man will say: Then protect yourself.
