Arabic hadith text
أَخْبَرَنَا مُحَمَّدُ بْنُ سَلَمَةَ، قَالَ حَدَّثَنَا ابْنُ الْقَاسِمِ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَا حَقُّ امْرِئٍ مُسْلِمٍ لَهُ شَىْءٌ يُوصَى فِيهِ يَبِيتُ لَيْلَتَيْنِ إِلاَّ وَوَصِيَّتُهُ مَكْتُوبَةٌ عِنْدَهُ " .
Translation
Muhammad ibn Salamah reported to us: Ibn al-Qasim narrated to us, from Malik, from Nafi', from Ibn 'Umar, that the Messenger of Allah (peace and blessings be upon him) said: ‘It is the right of a Muslim who has something to bequeath not to spend two nights without having his will written and kept with him.’
Translation notes
This is another wording of the report about keeping a written will at hand.
