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." (Using translation from Ibn Mājah 2040)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِنَّ اللهَ ﷻ تَجَاوَزَ لِأُمَّتِي عَنْ كُلِّ شَيْءٍ حَدَّثَتْ بِهِ أَنْفُسَهَا مَا لَمْ تَكَلَّمْ بِهِ أَوْ تَعْمَلْ بِهِ
