Hadith 17:94
Yazid ibn Harun narrated to us, he said: Fitr narrated to us, from Mujahid, from Abdullah ibn Amr, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The womb (kinship) is suspended from the Throne. The one who maintains ties is not the one who reciprocates (only when treated well), but the one who maintains ties is the one who, when his kinship is severed, maintains it."
حدثنا يزيد بن هارون قال حدثنا فطر عن مجاهد عن عبد الله بن عمرو قال قال رسول الله صلى الله عليه وسلم إن الرحم معلقة بالعرش وليس المواصل بالمكافىء ولكن الواصل الذي إذا [ قطعت ] رحمه وصلها
