"When 'Abdullah bin Ubayy died, his son came to the Prophet and said: 'Give me your shirt so that I may shroud him in it, and (some and) offer the (funeral) prayer for him, and pray for forgiveness for him'. So he gave him his shirt then he said: 'When you have finished, inform me and I will offer the (funeral) prayer for him.' But 'Umar stopped him and said: 'Hasn't Allah forbidden you to offer the (funeral) prayer for the hypocrites?' He said: 'I have two options. Whether you ask forgiveness for them (hypocrites) or ask no forgiveness for them." So he offered the (funeral) prayer for him. Then Allah, Most High, revealed: 'And never pray (funeral prayer) for any of them (hypocrites) who dies, nor stand at his grave.' So he stopped offering the (funeral) prayer for them."  

لَمَّا مَاتَ عَبْدُ اللَّهِ بْنُ أُبَىٍّ جَاءَ ابْنُهُ إِلَى النَّبِيِّ ﷺ فَقَالَ أَعْطِنِي قَمِيصَكَ حَتَّى أُكَفِّنَهُ فِيهِ وَصَلِّ عَلَيْهِ وَاسْتَغْفِرْ لَهُ فَأَعْطَاهُ قَمِيصَهُ ثُمَّ قَالَ إِذَا فَرَغْتُمْ فَآذِنُونِي أُصَلِّي عَلَيْهِ فَجَذَبَهُ عُمَرُ وَقَالَ قَدْ نَهَاكَ اللَّهُ أَنْ تُصَلِّيَ عَلَى الْمُنَافِقِينَ فَقَالَ أَنَا بَيْنَ خِيرَتَيْنِ قَالَ { اسْتَغْفِرْ لَهُمْ أَوْ لاَ تَسْتَغْفِرْ لَهُمْ } فَصَلَّى عَلَيْهِ فَأَنْزَلَ اللَّهُ تَعَالَى { وَلاَ تُصَلِّ عَلَى أَحَدٍ مِنْهُمْ مَاتَ أَبَدًا وَلاَ تَقُمْ عَلَى قَبْرِهِ } فَتَرَكَ الصَّلاَةَ عَلَيْهِمْ  

"The Prophet came to the grave of 'Abdullah bin Ubayy when he had been placed in his grave and stood over it. He commanded that he be brought out to him and placed on his knees, and he dressed him in his shirt and blew on him (for blessing). And Allah knows best."  

سَمِعْتُ جَابِرًا يَقُولُ أَتَى النَّبِيُّ ﷺ قَبْرَ عَبْدِ اللَّهِ بْنِ أُبَىٍّ وَقَدْ وُضِعَ فِي حُفْرَتِهِ فَوَقَفَ عَلَيْهِ فَأَمَرَ بِهِ فَأُخْرِجَ لَهُ فَوَضَعَهُ عَلَى رُكْبَتَيْهِ وَأَلْبَسَهُ قَمِيصَهُ وَنَفَثَ عَلَيْهِ مِنْ رِيقِهِ وَاللَّهُ تَعَالَى أَعْلَمُ  

"And Al-'Abass was in Al-Madinah, and he asked the Ansar for a garment to clothe him in, but they could not find a shirt that would fit him except the shirt of 'Abdullah bin Ubayy, so they clothed him in it."  

سَمِعَ جَابِرًا يَقُولُ وَكَانَ الْعَبَّاسُ بِالْمَدِينَةِ فَطَلَبَتِ الأَنْصَارُ ثَوْبًا يَكْسُونَهُ فَلَمْ يَجِدُوا قَمِيصًا يَصْلُحُ عَلَيْهِ إِلاَّ قَمِيصَ عَبْدِ اللَّهِ بْنِ أُبَىٍّ فَكَسَوْهُ إِيَّاهُ  

"We emigrated with the Messenger of Allah, seeking the Face of Allah, the Most High, so our reward became due from Allah. Some of us died without enjoying anything of his reward (in this world) among them is Mus'ab bin Umair. He was matyred on the day of Uhud and we could not find anything to shroud him in except a Namirah; if we covered his head with it, his feet were uncovered, and if we covered his feet with it, his head became uncovered. The Messenger of Allah told us to cover his head with it and to put Idhkhir over his feet. And for some of us, the fruits of our labor have ripened and we are gathering them." This is the wording of Isma'il  

هَاجَرْنَا مَعَ رَسُولِ اللَّهِ ﷺ نَبْتَغِي وَجْهَ اللَّهِ تَعَالَى فَوَجَبَ أَجْرُنَا عَلَى اللَّهِ فَمِنَّا مَنْ مَاتَ لَمْ يَأْكُلْ مِنْ أَجْرِهِ شَيْئًا مِنْهُمْ مُصْعَبُ بْنُ عُمَيْرٍ قُتِلَ يَوْمَ أُحُدٍ فَلَمْ نَجِدْ شَيْئًا نُكَفِّنُهُ فِيهِ إِلاَّ نَمِرَةً كُنَّا إِذَا غَطَّيْنَا رَأْسَهُ خَرَجَتْ رِجْلاَهُ وَإِذَا غَطَّيْنَا بِهَا رِجْلَيْهِ خَرَجَتْ رَأْسُهُ فَأَمَرَنَا رَسُولُ اللَّهِ ﷺ أَنْ نُغَطِّيَ بِهَا رَأْسَهُ وَنَجْعَلَ عَلَى رِجْلَيْهِ إِذْخِرًا وَمِنَّا مَنْ أَيْنَعَتْ لَهُ ثَمَرَتُهُ فَهُوَ يَهْدِبُهَا وَاللَّفْظُ لإِسْمَاعِيلَ
