Jami` at-Tirmidhi, Book 47, Hadith 3267 (In-Book) ⓘ
Narrated Anas: "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.'"
حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ بَكْرٍ السَّهْمِيُّ، حَدَّثَنَا حُمَيْدٌ، عَنْ أَنَسٍ، قَالَ لَمَّا نَزَلَتْ هَذِهِ الآيَةُ : ( لَنْ تَنَالُوا الْبِرَّ حَتَّى تُنْفِقُوا مِمَّا تُحِبُّونَ ) أَوْ : (مَنْ ذَا الَّذِي يُقْرِضُ اللَّهَ قَرْضًا حَسَنًا ) قَالَ أَبُو طَلْحَةَ وَكَانَ لَهُ حِائِطٌ فَقَالَ يَا رَسُولَ اللَّهِ حَائِطِي لِلَّهِ وَلَوِ اسْتَطَعْتُ أَنْ أُسِرَّهُ لَمْ أُعْلِنْهُ . فَقَالَ " اجْعَلْهُ فِي قَرَابَتِكَ أَوْ أَقْرَبِيكَ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ . وَقَدْ رَوَاهُ مَالِكُ بْنُ أَنَسٍ عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ عَنْ أَنَسِ بْنِ مَالِكٍ .
