وَعَنْ عَائِشَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَقُولُ لِنِسَائِهِ: «إِنَّ أَمْرَكُنَّ مِمَّا يَهُمُّنِي مِنْ بَعْدِي وَلَنْ يَصْبِرَ عَلَيْكُنَّ إِلَّا الصَّابِرُونَ الصِّدِّيقُونَ» قَالَتْ عَائِشَةُ: يَعْنِي الْمُتَصَدِّقِينَ ثُمَّ قَالَتْ عَائِشَةُ لِأَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ سَقَى اللَّهُ أَبَاكَ مِنْ سَلْسَبِيلِ الْجَنَّةِ وَكَانَ ابنُ عوفٍ قَدْ تَصَدَّقَ عَلَى أُمَّهَاتِ الْمُؤْمِنِينَ بِحَدِيقَةٍ بِيعَتْ بِأَرْبَعِينَ ألفا. رَوَاهُ التِّرْمِذِيّ
Translation

`A'isha told that God's messenger used to say to his wives, "I am concerned about what will happen to you after I am gone, when only the self-sacrificing and truly generous will continue to care for you." `A'isha said his meaning was those who give sadaqa. Then `A'isha said to Abu Salama b. `Abd ar-Rahman, "May God give your father drink from Salsabil[1] in paradise!" Ibn `Auf[2] had given as sadaqa for the mothers of the faithful a garden which had been sold for forty thousand. A fountain in paradise. Cf. Quran, 76:18. i.e., 'Abd ar-Rahman b. `Auf, Abu Salama's father. Tirmidhi transmitted it.
