call to believers

رَبِّ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ وَمَا بَيْنَهُمَآ ۖ إِن كُنتُم مُّوقِنِينَ

Lord of the heavens and the earth and that between them, if you would be certain.

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ هَلْ أَدُلُّكُمْ عَلَىٰ تِجَـٰرَةٍ تُنجِيكُم مِّنْ عَذَابٍ أَلِيمٍ

O you who have believed, shall I guide you to a transaction that will save you from a painful punishment?
