عَنْ مُصْعَبِ بْنِ سَعْدٍ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ قَالَ حَلَفْتُ بِاللَّاتِ وَالْعُزَّى فَقَالَ أَصْحَابِي قَدْ قُلْتَ هُجْرًا فَأَتَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقُلْتُ إِنَّ الْعَهْدَ كَانَ قَرِيبًا وَإِنِّي حَلَفْتُ بِاللَّاتِ وَالْعُزَّى فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قُلْ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ ثَلَاثًا ثُمَّ انْفُثْ عَنْ يَسَارِكَ ثَلَاثًا وَتَعَوَّذْ وَلَا تَعُدْ
It is narrated from Sayyiduna Sa’d (may Allah be pleased with him), he says: I swore by Lat and ‘Uzza. My companions said to me: You have spoken an evil word. So I came to the Noble Prophet (peace and blessings be upon him) and said: Our time of ignorance is still near, and I have sworn by Lat and ‘Uzza. The Messenger of Allah (peace and blessings be upon him) said: Say three times, “There is no god but Allah, alone,” then spit three times to your left and seek refuge (in Allah), and do not swear such an oath again.
