tabarani:638[Chain 1] Muḥammad b. al-Faḍl al-Saqaṭī > Saʿīd b. Sulaymān [Chain 2] al-Ḥusayn b. Isḥāq al-Tustarī > ʿAlī b. Baḥr > ʿĪsá b. Yūnus > Mujālid > al-Shaʿbī > al-Ashʿath b. Qays > Khāṣam a man from al-Ḥaḍramiyyīn a man Minnā

[Machine] "A man from the Hadrami people disputed with a man from our group, known as al-Hafshish, in the presence of the Prophet, ﷺ , in a land that belonged to him. The Prophet, ﷺ , said to the Hadrami man, 'Bring your witnesses regarding your right, or else he can take an oath.' The Hadrami man said, 'I consider my land to be more important than not swearing an oath on it.' The Messenger of Allah, ﷺ , said, 'The Muslim's oath is binding according to what he has testified to, even if it is less significant than that.' The man left to swear an oath, and the Prophet, ﷺ , said, 'If he swears falsely, Allah will enter him into the Hellfire.' Then al-Ash'ath came and informed the Prophet, ﷺ , that they had reconciled."  

الطبراني:٦٣٨حَدَّثَنَا مُحَمَّدُ بْنُ الْفَضْلِ السَّقَطِيُّ ثنا سَعِيدُ بْنُ سُلَيْمَانَ ح وَحَدَّثَنَا الْحُسَيْنُ بْنُ إِسْحَاقَ التُّسْتَرِيُّ ثنا عَلِيُّ بْنُ بَحْرٍ قَالَا ثنا عِيسَى بْنُ يُونُسَ عَنْ مُجَالِدٍ عَنِ الشَّعْبِيِّ عَنِ الْأَشْعَثِ بْنِ قَيْسٍ قَالَ

خَاصَمَ رَجُلٌ مِنَ الْحَضْرَمِيِّينَ رَجُلًا مِنَّا يُقَالُ لَهُ الْحَفْشِيشُ إِلَى النَّبِيِّ ﷺ فِي أَرْضٍ لَهُ فَقَالَ النَّبِيُّ ﷺ لِلْحَضْرَمِيِّ «جِئْ بِشُهُودِكَ عَلَى حَقِّكَ وَإِلَّا حَلَفَ لَكَ» قَالَ لَهُ أَرْضِي أَعْظَمُ شَأْنًا مِنْ أَنْ لَا يَحْلِفَ عَلَيْهَا فَقَالَ رَسُولُ اللهِ ﷺ «إِنَّ يَمِينَ الْمُسْلِمِ مِنْ وَرَاءِ مَا هُوَ أَعْظَمُ مِنْ ذَلِكَ» فَانْطَلَقَ لِيَحْلِفَ فَقَالَ النَّبِيُّ ﷺ «إِنْ هُوَ حَلَفَ كَاذِبًا أَدْخَلَهُ اللهُ ﷻ النَّارَ» فَانْطَلَقَ الْأَشْعَثُ فَأَخْبَرَهُ فَقَالَ أَصْلِحْ بَيْنِي وَبَيْنَهُ فَأَصْلَحَ بَيْنَهُمَا
