"When this Verse was revealed -'By no means shall you attain Al Birr (piety, righteousness--here it means Allah's reward, i.e. Paradise), unless you spend (in Allah's cause) of that which you love'- Abu Talha said: 'Our Lord will ask us about our wealth. I adjure you, O Messenger of Allah! I am giving my land to Allah.' The Messenger of Allah said: 'Make it for your relatives, Hassan bin Thabit and Ubayy bin Ka'b.'" (Using translation from Nasāʾī 3602)
لَمَّا نَزَلَتْ هَذِهِ الْآيَةُ {لَنْ تَنَالُوا الْبِرَّ حَتَّى تُنْفِقُوا مِمَّا تُحِبُّونَ} [آل عمران 92] قَالَ أَبُو طَلْحَةَ أَرَى رَبَّنَا يَسْأَلُنَا مِنْ أَمْوَالِنَا فَأُشْهِدُكَ يَا رَسُولَ اللهِ أَنِّي قَدْ جَعَلْتُ أَرْضِي لِلَّهِ فَقَالَ رَسُولُ اللهِ ﷺ «اجْعَلْهَا فِي قَرَابَتِكَ فِي حَسَّانَ بْنِ ثَابِتٍ وَأُبَيِّ بْنِ كَعْبٍ»
