"When this Ayah was revealed: By no means shall you attain Al-Birr unless you spend of that which you love (3:92). Or, '...Who is he that will lend to Allah a goodly loan... (2:245)' Abu Talhah - who had a garden - said: 'O Messenger of Allah! My garden is for Allah, and if I was able to keep it secret I would not make it public.' So he said: 'Keep it for your relatives' or 'your close relatives.'" (Using translation from Tirmidhī 2997)
لَمَّا نَزَلَتْ {لَنْ تَنَالُوا الْبِرَّ حَتَّى تُنْفِقُوا مِمَّا تُحِبُّونَ} [آل عمران 92] وَ {مَنْ ذَا الَّذِي يُقْرِضُ اللهَ قَرْضًا حَسَنًا} [البقرة 245] قَالَ أَبُو طَلْحَةَ يَا رَسُولَ اللهِ حَائِطِي الَّذِي بِمَكَانِ كَذَا وَكَذَا وَاللهِ لَوِ اسْتَطَعْتُ أَنْ أُسِرَّهَا لَمْ أُعْلِنْهَا فَقَالَ اجْعَلْهُ فِي فُقَرَاءِ أَهْلِكَ
