Sayyiduna Anas (may Allah be pleased with him) narrates: A man asked the Noble Prophet (peace and blessings be upon him):“How many prayers has Allah made obligatory upon His servants?”The Noble Prophet (peace and blessings be upon him) said:“Five prayers.”He asked:“Is there any obligatory prayer before or after these?”The Noble Prophet (peace and blessings be upon him) said:“Allah the Exalted has made five prayers obligatory upon His servants.”So that man swore by the name of Allah that he would neither add to them nor decrease from them. The Noble Prophet (peace and blessings be upon him) said:“If he is speaking the truth, he will enter Paradise.”
