“The Muslim man has no right to spend two nights, if he has something for which will should be made, without having a written will with him.” (Using translation from Ibn Mājah 2702)
عَنِ النَّبِيِّ ﷺ قَالَ مَا حَقُّ امْرِئٍ يَبِيتُ لَيْلَتَيْنِ وَلَهُ مَا يُرِيدُ أَنْ يُوصِيَ فِيهِ إِلَّا وَوَصِيَّتُهُ مَكْتُوبَةٌ عِنْدَهُ
