سُنَنُ ابْنِ مَاجَهْ
Sunan Ibn Majah 2097
The Chapters on Expiation
Prohibition of making an oath by other than Allah
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، وَالْحَسَنُ بْنُ عَلِيٍّ الْخَلاَّلُ، قَالاَ حَدَّثَنَا يَحْيَى بْنُ آدَمَ، عَنْ إِسْرَائِيلَ، عَنْ أَبِي إِسْحَاقَ، عَنْ مُصْعَبِ بْنِ سَعْدٍ، عَنْ سَعْدٍ، قَالَ حَلَفْتُ بِاللاَّتِ وَالْعُزَّى فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ قُلْ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ ثُمَّ انْفُثْ عَنْ يَسَارِكَ ثَلاَثًا وَتَعَوَّذْ وَلاَ تَعُدْ .
It was narrated that Sa'd said: "I took an oath by Lat and 'Uzza. The Messenger of Allah (ﷺ) said : 'Say: "La ilaha illallah wahdahu la sharika lahu" (None has the right to be worshipped but Allah alone, with no partner or associate)," then spit toward your left three times, and seek refuge with Allah, and do not do that again."'
