It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Whoever, after hearing the call of the muezzin, supplicates: "O Allah, Lord of this perfect call and established prayer, grant Muhammad the means and virtue, and raise him to the station which You have promised him," then my intercession will become obligatory for him on the Day of Resurrection.
