عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «بَلِّغُوا عَنِّي وَلَوْ آيَةً وَحَدِّثُوا عَنْ بَنِي إِسْرَائِيلَ وَلَا حَرَجَ وَمَنْ كَذَبَ عَلَيَّ مُتَعَمِّدًا فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ» . رَوَاهُ البُخَارِيّ

Abu Huraira reported God’s messenger as saying, “When a man dies no further reward is recorded for his actions, with three exceptions

sadaqa which continues to be supplied, or knowledge from which benefitcontinues to be reaped, or the prayers of a good son for his dead father.”Muslim transmitted it.
