Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: Praying is dearer to me than fasting. (The narrator states:) He did not perform the forenoon (Duha) prayer.
This narration was recorded by Imam al-Tabarani in al-Mu'jam al-Kabir; its chain contains a narrator, Bukayr bin Amir, whom Imam Ahmad declared "thiqah" (trustworthy), while Yahya bin Ma'in and a group declared him da'if (weak).
