[Machine] I asked Abdullah bin Abi Aufa, "Did the Messenger of Allah ﷺ leave any will?" He replied, "The Messenger of Allah ﷺ did not leave anything without giving instructions about it." I asked, "How then does he instruct the people about writing wills?" He said, "He gave instruction with the Book of Allah."  

سَأَلْتُ عَبْدَ اللَّهِ بْنَ أَبِي أَوْفَى «هَلْ أَوْصَى رَسُولُ اللَّهِ ﷺ؟ قَالَ مَا تَرَكَ رَسُولُ اللَّهِ ﷺ شَيْئًا يُوصِي فِيهِ قُلْتُ فَكَيْفَ يَأْمُرُ النَّاسَ بِالْوَصِيَّةِ؟ قَالَ » أَوْصَى بِكِتَابِ اللَّهِ «  

The Messenger of Allah ﷺ as saying: It is the duty of a Muslim man who has something which is to be given as bequest not to have it for two nights without having his will written regarding it. (Using translation from Abū Dāʾūd 2862)  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَا حَقُّ امْرِئٍ مُسْلِمٍ لَهُ شَيْءٌ يُوصِي فِيهِ يَبِيتُ لَيْلَتَيْنِ إِلَّا وَوَصِيَّتُهُ مَكْتُوبَةٌ عِنْدَهُ»  

[Machine] Hijara Ubaidullah ibn Jahsh emigrated to the land of Abyssinia with his wife Umm Habiba bint Abi Sufyan. When they arrived in Abyssinia, he fell ill. When death approached him, he entrusted the Prophet Muhammad ﷺ . The Prophet Muhammad ﷺ married Umm Habiba and sent the Negus, Ashama bin Hasanah, with her.  

هَاجَرَ عُبَيْدُ اللَّهِ بْنُ جَحْشٍ بِأُمِّ حَبِيبَةَ بِنْتِ أَبِي سُفْيَانَ وَهِيَ امْرَأَتُهُ إِلَى أَرْضِ الْحَبَشَةِ فَلَمَّا قَدِمَ أَرْضَ الْحَبَشَةِ مَرِضَ فَلَمَّا حَضَرَتْهُ الْوَفَاةُ أَوْصَى إِلَى رَسُولِ اللَّهِ ﷺ فَتَزَوَّجَ رَسُولُ اللَّهِ ﷺ أُمَّ حَبِيبَةَ وَبَعَثَ مَعَهَا النَّجَاشِيُّ شُرَحْبِيلَ بْنَ حَسَنَةَ «  

[Machine] The Messenger of Allah ﷺ said, "It is not permissible for a Muslim that three nights should pass by him without having a will written."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَا حَقُّ امْرِئٍ مُسْلِمٍ تَمُرُّ عَلَيْهِ ثَلَاثُ لَيَالٍ إِلَّا وَوَصِيَّتُهُ عِنْدَهُ»  

That his father said, "In the year of the last Hajj of the Prophet ﷺ I became seriously ill and the Prophet ﷺ used to visit me inquiring about my health. I told him, 'I am reduced to this state because of illness and I am wealthy and have no inheritors except a daughter, (In this narration the name of 'Amir bin Saʿd is mentioned and in fact it is a mistake; the narrator is ʿAisha bint Saʿd bin Abi Waqqas). Should I give two-thirds of my property in charity?' He said, 'No.' I asked, 'Half?' He said, 'No.' then he added, 'Onethird, and even one-third is much. You'd better leave your inheritors wealthy rather than leaving them poor, begging others. You will get a reward for whatever you spend for Allah's sake, even for what you put in your wife's mouth.' I said, 'O Messenger of Allah ﷺ! Will I be left alone after my companions have gone?' He said, 'If you are left behind, whatever good deeds you will do will upgrade you and raise you high. And perhaps you will have a long life so that some people will be benefited by you while others will be harmed by you. O Allah! Complete the emigration of my companions and do not turn them renegades.' But Messenger of Allah ﷺ felt sorry for poor Saʿd bin Khaula as he died in Mecca." (but Saʿd bin Abi Waqqas lived long after the Prophet ﷺ.) (Using translation from Bukhārī 1295)  

أَنَّهُ قَالَ جَاءَنِي رَسُولُ اللَّهِ ﷺ يَعُودُنِي عَامَ حَجَّةِ الْوَدَاعِ مِنْ وَجَعٍ اشْتَدَّ بِي فَقُلْتُ يَا رَسُولَ اللَّهِ بَلَغَ بِي مِنَ الْوَجَعِ مَا تَرَيْ وَأَنَا ذُو مَالٍ وَلَا يَرِثُنِي إِلَّا ابْنَةٌ لِي أَفَأَتَصَدَّقُ بِثُلُثَيْ مَالِي؟ قَالَ «لَا» قُلْتُ فَبِشَطْرِهِ؟ قَالَ «لَا» ثُمَّ قَالَ «الثُّلُثُ وَالثُّلُثُ كَثِيرٌ أَوْ كَبِيرٌ إِنَّكَ إِنْ تَذَرْ وَرَثَتَكَ أَغْنِيَاءَ خَيْرٌ مِنْ أَنْ يَكُونُوا عَالَةً يَتَكَفَّفُونَ النَّاسَ وَإِنَّكَ لَنْ تُنْفِقَ نَفَقَةً تَبْتَغِي بِهَا وَجْهَ اللَّهِ إِلَّا أُجِرْتَ بِهِ حَتَّى مَا تَجْعَلُ فِي فِي امْرَأَتِكَ» فَقُلْتُ يَا رَسُولَ اللَّهِ أُخَلَّفُ بَعْدَ أَصْحَابِي؟ قَالَ «إِنَّكَ لَنْ تُخَلَّفَ فَتَعْمَلَ عَمَلًا صَالِحًا تَبْتَغِي بِهِ وَجْهَ اللَّهِ إِلَّا ازْدَدْتَ بِهِ دَرَجَةً وَرِفْعَةً وَلَعَلَّكَ أَنْ تُخَلَّفَ حَتَّى يَنْتَفِعَ بِكَ أَقْوَامٌ وَيُضَرَّ بِكَ آخَرُونَ اللَّهُمَّ أَمْضِ لِأَصْحَابِي هِجْرَتَهُمْ وَلَا تَرُدَّهُمْ عَلَى أَعْقَابِهِمْ لَكِنَّ الْبَائِسَ سَعْدَ بْنَ خَوْلَةَ» يَرْثِي لَهُ رَسُولُ اللَّهِ ﷺ أَنْ مَاتَ بِمَكَّةَ
