The grandfather of Abdullah bin Qudamah al-Jumahi relates: I heard Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) saying: "I heard the Prophet (peace and blessings be upon him) saying: 'O Allah, strengthen Islam through Umar bin al-Khattab.'"
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is not narrated from Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) except with this chain, and al-Zubayr bin Abbad is alone in narrating it."
