12- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ بْنِ صَدَقَةَ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ قَالَ النَّبِيُّ (صَلَّى اللهُ عَلَيْهِ وَآلِه) اغْزُوا تُورِثُوا أَبْنَاءَكُمْ مَجْداً.
12. Ali ibn Ibrahim has narrated from his father from Harun ibn Muslim from Mas’adah ibn Sadaqah who has said the following: “Abu ‘Abd Allah (a.s.), has said that the Messenger of Allah has said, ‘Fight (for the cause of Allah) and leave glory as your legacy for your children.’”
