How to swear?
قَالَ تَعَالَى: {يَحْلِفُونَ بِاللَّهِ لَكُمْ}. وَقَوْلُهُ عَزَّ وَجَلَّ: {ثُمَّ جَاءُوكَ يَحْلِفُونَ بِاللَّهِ إِنْ أَرَدْنَا إِلاَّ إِحْسَانًا وَتَوْفِيقًا} يُقَالُ بِاللَّهِ وَتَاللَّهِ وَوَاللَّهِ. وَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «وَرَجُلٌ حَلَفَ بِاللَّهِ كَاذِبًا بَعْدَ الْعَصْرِ». وَلاَ يُحْلَفُ بِغَيْرِ اللَّهِ.Allah تعالى said: “They swear by Allah…” (V.9:56, 62, 74, 95). And Allah عز وجل said: “…They come to you swearing by Allah: ‘We meant no more than goodwill and conciliation’.” (V.4:62) The expressions used in Arabic for ‘By Allah’ are: Bil-lahi, Tal-lahi, Wal-lahi. The Prophet ﷺ said, “And a man who takes a false oath in the Name of Allah after the ‘Asr prayer. The Prophet ﷺ said, ‘One should not swear except by Allah.’”
Sahih Bukhari
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جُوَيْرِيَةُ، قَالَ ذَكَرَ نَافِعٌ عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " مَنْ كَانَ حَالِفًا فَلْيَحْلِفْ بِاللَّهِ أَوْ لِيَصْمُتْ ".
Narrated `Abdullah: The Prophet (ﷺ) said, "Whoever has to take an oath should swear by Allah or remain silent." (i.e. He should not swear by other than Allah.)
