(13) باب إِبْرَارِ الْقَسَمِ
Al-Bara' bin 'Azib said:
"The Messenger of Allah commanded us to do seven things: He commanded us to attend funerals, visit the sick, to reply (say: Yarhamuk Allah [may Allah have mercy on you]) to one who sneezes, to accept invitations, to support the oppressed, to fulfill oaths (when adjured by another) and to return greetings of Salaam."
