It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) entered the mosque while the Prophet (peace and blessings be upon him) was delivering the sermon. He sat down beside Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) and asked him about some matter, but he gave him no reply, at which Ibn Mas'ud (may Allah be pleased with him) thought that perhaps he was displeased with him. Then he mentioned this to the Prophet (peace and blessings be upon him). Then Sayyiduna Ubayy (may Allah be pleased with him) said: "O Abdullah! You were not present with us at the Friday prayer at all (in terms of reward and merit)." He asked: "Why is that?" He replied: "Because you spoke while the Prophet (peace and blessings be upon him) was delivering the sermon." At that the Prophet (peace and blessings be upon him) said: "Ubayy has spoken the truth."
Imam Abu Ya'la recorded this hadith in his Musnad. Although the memory of Isa bin Jariyah in its chain has been criticised, other sahih hadith about losing the merits of the Friday prayer by talking during the sermon support its meaning.
