What a man says in supplication when the prayer is established

Abu Ishaq said that al-Hakam said: Whoever hears the caller announcing the establishing of the prayer, let him supplicate thus: "O Allah, Lord of this complete call and of the prayer that is being established, grant Muhammad his request on the Day of Resurrection." Because of this, intercession will be made for him.

Abu Hamzah said that al-Hasan said: When you hear the caller to prayer saying: "The prayer has indeed been established," then supplicate thus: "O Allah, Lord of this complete call and of the prayer that is being established, grant Muhammad (peace and blessings be upon him) his request on the Day of Resurrection." No man says this supplication when the caller stands except that Allah will admit that man into the intercession of Muhammad (peace and blessings be upon him) on the Day of Resurrection.

Qatadah said that when Sayyiduna Uthman (may Allah be pleased with him) heard the caller to prayer saying these words: "The prayer has indeed been established," he would say: "Well done, you who speak what is just, and welcome, O prayer." Then he would stand up for the prayer.

When Mujahid heard the caller to prayer say: "Come to the prayer," he would say: "With the help of Allah." And when the caller said: "Come to success," he would say: "There is no power to avoid sins and no strength to do good except with the help of Allah."

Sayyiduna Abdullah bin al-Harith (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) used to say just as the caller to prayer said. When the caller said: "Come to the prayer, come to success," he (peace and blessings be upon him) would say: "There is no power to avoid sins and no strength to do good except with the help of Allah."
