عن عبد الله بن عمرو رضي الله عنهما عن النبي صلى الله عليه وسلم قال: «لَيْسَ الْوَاصِلُ بِالْمُكَافِئِ، وَلَكِنِ الْوَاصِلُ الَّذِي إِذَا قُطِعَتْ رَحِمُهُ وَصَلَهَا».
Imepokelewa Kutoka kwa Abdillah Ibn Amri -Radhi za Allah ziwe juu yao wawili- kutoka kwa Mtume -Rehema na amani ziwe juu yake-amesema: "Muunga udugu si mlipa fadhila, bali muunga udugu ni yule ambaye udugu wake ukikatwa anauunga".
‘Abdullāh ibn ‘Amr (may Allah be pleased with him) reported: The Prophet (may Allah’s peace and blessings be upon him) said: "The one who maintains ties of kinship is not the one who recompenses the good done to him by his relatives; rather, he is the one who keeps good relations with those relatives who severs the bond of kinship with him."
Kuunga udugu kunakozingatiwa kisheria ni kumuunga aliyekukata miongoni mwao, na kumsamehe aliyekudhulumu, na kumpa aliyekunyima, na si kuunga udugu kwa kubadilishana (wakiniunga nitawaunga wakikata nawakata) au kulipa wema uliotendewa.
Kuunga udugu kunakuwa kwa kufikisha kheri kwa kadiri ya uwezo, kwa kutumia mali na dua na kuamrishana mema na kukatazana maovu na mfano wake, na kuzuia yawezekanayo katika shari juu yao.
