﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ هَلْ أَدُلُّكُمْ عَلَىٰ تِجَٰرَةٍۢ تُنجِيكُم مِّنْ عَذَابٍ أَلِيمٍۢ ﴾

“O YOU who have attained to faith! Shall I point out to you a bargain that will save you from grievous suffering [in this world and in the life to come]?”

(O ye who believe!) And He explained who they are at the beginning of the surah (Shall I show you a commerce that will save you from a painful doom) in the Hereafter?
