عَنْ عَبْدِ اللَّهِ بْنِ سَلَامٍ قَالَ: لَمَّا قَدِمَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْمَدِينَةَ جِئْتُ فَلَمَّا تَبَيَّنْتُ وَجْهَهُ عَرَفْتُ أَنَّ وَجْهَهُ لَيْسَ بِوَجْهِ كَذَّابٍ. فَكَانَ أَوَّلُ مَا قَالَ: «أَيُّهَا النَّاسُ أَفْشُوا السَّلَامَ وَأَطْعِمُوا الطَّعَامَ وَصِلُوا الْأَرْحَامَ وَصَلُّوا بِاللَّيْلِ وَالنَّاسُ نِيَامٌ تَدْخُلُوا الْجَنَّةَ بِسَلام» . رَوَاهُ التِّرْمِذِيّ وَابْن مَاجَه والدارمي

Sa‘d b. ‘Ubada told God’s messenger that Umm Sa'd had died and asked him what form of sadaqa was best. When he replied that water was best, he dug a well and said it was for Umm Sa'd. Abu Dawud and Nasa’i transmitted it.
