Abu Talha and the Prophet ﷺ used to shield themselves with one shield. Abu Talha was a good archer, and when he threw (his arrows) the Prophet ﷺ would look at the target of his arrows.  

كَانَ أَبُو طَلْحَةَ يَتَتَرَّسُ مَعَ النَّبِيِّ ﷺ بِتُرْسٍ وَاحِدٍ وَكَانَ أَبُو طَلْحَةَ حَسَنَ الرَّمْىِ فَكَانَ إِذَا رَمَى تَشَرَّفَ النَّبِيُّ ﷺ فَيَنْظُرُ إِلَى مَوْضِعِ نَبْلِهِ  

When the helmet of the Prophet ﷺ was smashed on his head and blood covered his face and one of his front teeth got broken, ʿAli brought the water in his shield and Fatima the Prophet's daughter) washed him. But when she saw that the bleeding increased more by the water, she took a mat, burnt it, and placed the ashes on the wound of the Prophet ﷺ and so the blood stopped oozing out.  

لَمَّا كُسِرَتْ بَيْضَةُ النَّبِيِّ ﷺ عَلَى رَأْسِهِ وَأُدْمِيَ وَجْهُهُ وَكُسِرَتْ رَبَاعِيَتُهُ وَكَانَ عَلِيٌّ يَخْتَلِفُ بِالْمَاءِ فِي الْمِجَنِّ وَكَانَتْ فَاطِمَةُ تَغْسِلُهُ فَلَمَّا رَأَتِ الدَّمَ يَزِيدُ عَلَى الْمَاءِ كَثْرَةً عَمَدَتْ إِلَى حَصِيرٍ فَأَحْرَقَتْهَا وَأَلْصَقَتْهَا عَلَى جُرْحِهِ فَرَقَأَ الدَّمُ  

The properties of Bani An-Nadir which Allah had transferred to His Apostle as Fai Booty were not gained by the Muslims with their horses and camels. The properties therefore, belonged especially to Messenger of Allah ﷺ who used to give his family their yearly expenditure and spend what remained thereof on arms and horses to be used in Allah's Cause.  

كَانَتْ أَمْوَالُ بَنِي النَّضِيرِ مِمَّا أَفَاءَ اللَّهُ عَلَى رَسُولِهِ ﷺ مِمَّا لَمْ يُوجِفِ الْمُسْلِمُونَ عَلَيْهِ بِخَيْلٍ وَلاَ رِكَابٍ فَكَانَتْ لِرَسُولِ اللَّهِ ﷺ خَاصَّةً وَكَانَ يُنْفِقُ عَلَى أَهْلِهِ نَفَقَةَ سَنَتِهِ ثُمَّ يَجْعَلُ مَا بَقِيَ فِي السِّلاَحِ وَالْكُرَاعِ عُدَّةً فِي سَبِيلِ اللَّهِ  

I never saw the Prophet ﷺ saying, "Let my parents sacrifice their lives for you," to any man after Saʿd. I heard him saying (to him), "Throw (the arrows)! Let my parents sacrifice their lives for you."  

سَمِعْتُ عَلِيًّا ؓ يَقُولُ مَا رَأَيْتُ النَّبِيَّ ﷺ يُفَدِّي رَجُلاً بَعْدَ سَعْدٍ سَمِعْتُهُ يَقُولُ ارْمِ فِدَاكَ أَبِي وَأُمِّي
