Messenger of Allah ﷺ said, "Verily, one of the worst lies is to claim falsely to be the son of someone other than one's real father, or to claim to have had a dream one has not had, or to attribute to me what I have not said."

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ مِنْ أَعْظَمِ الْفِرَى أَنْ يَدَّعِيَ الرَّجُلُ إِلَى غَيْرِ أَبِيهِ أَوْ يُرِيَ عَيْنَهُ مَا لَمْ تَرَ أَوْ يَقُولُ عَلَى رَسُولِ اللَّهِ ﷺ مَا لَمْ يَقُلْ

[Machine] I heard the Messenger of Allah ﷺ saying, "The greatest of lies are three: for a man to fabricate seeing something with his eyes when he did not see it, and to fabricate against his parents by claiming to have been called by someone other than his father, or to say 'He heard from me' when he did not hear from me."

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ أَعْظَمَ الْفِرَى ثَلَاثَةٌ أَنْ يَفْتَرِيَ الرَّجُلُ عَلَى عَيْنَيْهِ يَقُولُ رَأَيْتُ وَلَمْ يَرَ وَأَنْ يَفْتَرِيَ عَلَى وَالِدَيْهِ فَيَدَّعِي إِلَى غَيْرِ أَبِيهِ أَوْ يَقُولُ سَمِعَنِي وَلَمْ يَسْمَعْ مِنِّي

[Machine] "The greatest of lies is for a man to claim to be someone's father when he is not, or for him to see in a dream something that his eyes have not seen, or to attribute something to the Messenger of Allah that he did not say."

نَبِيُّ اللهِ ﷺ إِنَّ مِنْ أَعْظَمِ الْفِرَى أَنْ يُدْعَى الرَّجُلُ إِلَى غَيْرِ أَبِيهِ أَوْ يُرِيَ عَيْنَيْهِ فِي الْمَنَامِ مَا لَمْ تَرَيَا أَوْ يَقُولَ عَلَى رَسُولِ اللهِ ﷺ مَا لَمْ يَقُلْ

[Machine] The Messenger of Allah, ﷺ , said: The greatest liar is the one who attributes words to me that I have not said, and the one who claims to see with his eyes in a dream what he has not seen, and the one who claims to be a son of someone other than his father.

قَالَ رَسُولُ اللهِ ﷺ أَعْظَمُ الْفِرَى مَنْ يُقَوِّلُنِي مَا لَمْ أَقُلْ وَمَنْ أَرَى عَيْنَيْهِ فِي الْمَنَامِ مَا لَمْ تَرَ وَمَنْ ادَّعَى إِلَى غَيْرِ أَبِيهِ

"إِنَّ من أَعْظم الْفِرَى أَن يُدعى الرَّجُلُ إِلى غَيْرِ أَبِيهِ، أَو يُرِى عَيْنَهُ في المنامِ ما لم تَر، أَوْ يقولَ على رسولِ اللَّه ما لم يَقُلْ".
