Majma al-Zawaid — Hadith 13980

In one narration the words are: "I have been commanded to pray the two rak'ahs of Duha (the forenoon prayer) and to pray Witr, and these have not been made obligatory upon you." Ahmad recorded all of these narrations with various chains; al-Bazzar recorded similar narrations in abridged form; and al-Tabarani recorded them in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat. In their narration the words are: "There are three things which are obligatory upon me." Its chain contains Abu Janab al-Kalbi, who is a mudallis (one who conceals defects in his chain). The remaining narrators of this narration as recorded by Ahmad are the narrators of the Sahih, and the rest of its chains contain Jabir al-Ju'fi, who is da'if (weak).
