Ja'far bin Muhammad (may Allah have mercy on him) narrates from his father that the Prophet (peace and blessings be upon him) entered (the mosque) when the iqamah for the morning prayer had been called, and he passed by Ibn al-Qishb (may Allah be pleased with him). He (peace and blessings be upon him) said: "Will you pray four rak'ahs for the morning prayer?"
