Hadith text
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)
Abdullah (رضی اللہ عنہ) bataate hain: Nabi ne kaha: "Jise bhi qasam leni ho, use Allah ke naam ki qasam leni chahiye ya khaamosh rehna chahiye." (Yaani use Allah ke ilawa kisi aur ki qasam nahi leni chahiye.)
