كتاب الطلاق
Read the English translation first, with the original Arabic directly underneath.
It was narrated from Abu Hurairah that:
the Messenger of Allah (ﷺ) said: "Allah has forgiven my nation for what they think of to themselves, so long as they do not act upon it or speak of it."
إِنَّ اللَّهَ تَجَاوَزَ لأُمَّتِي عَمَّا حَدَّثَتْ بِهِ أَنْفُسَهَا مَا لَمْ تَعْمَلْ بِهِ أَوْ تَكَلَّمْ بِهِ
