Forty Ahadith on Parents

  1. Visiting the Graves of Parents  ===================================

قَالَ رَسُولُ اللٌّهُ (ص): مَنْ زَارَ قَبْرَ وَالِدَيهِ أَوْ أَحَدِهِمَا فِي كُلِّ جُمْعَةٍ مَرَّةً غَفَرَ اللٌّهُ لَهُ وَ كَتَبَ لَهُ بَارًّا.

It has been narrated that the Messenger of Allah (peace be upon him and his family) said: “Whoever visits the graves of his parents or one of them every Friday, Allah shall forgive his sins and shall regard him to be of those who had been kind to his parents.”
