It is narrated from Ibn Abi Mulaykah that Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with him) wrote to the people of Iraq that the one about whom the Messenger of Allah (peace and blessings be upon him) said: "If I were to take anyone as a khalil, I would take Abu Bakr as a khalil" — that same Abu Bakr (may Allah be pleased with him) said: The grandfather is like the father.
