Majma al-Zawaid — Hadith 16831

Sayyiduna Abu al-Mundhir al-Juhani (may Allah be pleased with him) states: I said: "O Prophet of Allah, teach me the most excellent speech." The Prophet (peace and blessings be upon him) said: "O Abu al-Mundhir, recite: 'La ilaha illallahu wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu, yuhyi wa yumitu, biyadihil-khayru, wa huwa 'ala kulli shay'in qadir' (There is no deity except Allah; He alone is the deity, He has no partner; to Him alone belongs the dominion, to Him alone belongs all praise; He gives life, He gives death; all good is in His hand, and He has power over all things). (The Prophet, peace and blessings be upon him, said:) Recite it one hundred times every day, and on that day you will be the most excellent of people in deeds, except for one who recited as much as you recited." (Allamah Haythami says:) I say: After this he mentioned the complete narration, which is given in full in the chapter on the enduring good deeds (al-baqiyat al-salihat).
Bazzar recorded it; its chain contains a narrator, Jabir al-Ju'fi, who is da'if (weak).
