He returned the salam and said: "Go back and pray, for you have not prayed.'" He (the narrator) said: "I do not know if it was the second or third time,- "(the man) said: 'By the One Who revealed the Book to you, I have tried my best. Teach me and show me.' He said: 'When you want to pray, perform wudu' and do it well, then stand up and face the qiblah. Then say the takbir, then recite, then bow until you are at ease in bowing. Then stand up until you are standing up straight. Then prostrate until you are at ease in prostration, then raise your head until you are at ease in sitting, then prostrate until you are at ease in prostration. If you do that then you will have done your prayer properly, and whatever you failed to do properly is going to detract from your prayer."

When he recites 'Not (the way) of those who earned Your anger, nor those who went astray' then say: "Amin" and Allah will answer you. When he says the takbir and bows, then say the takbir and bow. The Imam bows before you do and stands up before you do.' The Prophet (ﷺ) of Allah (ﷺ) said: 'This makes up for that. And when he says: "'Sami Allahu liman hamidah (Allah hears the one who praises Him),' then say: "Allahumma Rabbana wa lakal-hamd (O Allah, our Lord, and to You be the praise), " Allah will hear you, for Allah has said on the lips of His Prophet (ﷺ): "Allah hears the one who praises Him." And when he (the Imam) says the takbir and prostrates, then say the takbir and prostrate. The Imam prostrates before you do and sits up before you do.' The Prophet (ﷺ) of Allah (ﷺ) said: 'This makes up for that. And when he is sitting, let the first thing that any one of you says be: At-tahiyaatut-tayyibatus-salawatuLillah, salamun 'alayka ayyuhanabiyyu wa rahmatullahi wa barakatuhu, salamun 'alayna wa 'ala 'ibadillahis-salihin, ashhadu an la ilaha ill-Allah wa ashhadu anna Muhammadan 'abduhu wa rasuluh (All compliments, good words and prayers are due to Allah, peace be upon you O Prophet, and the mercy of Allah and His blessings. Peace be upon us and upon the righteous slaves of Allah. I bear witness that there is none worthy of worship except Allah and I bear witness that Muhammad is His slave and Messenger)- seven phrases which are the greeting of the prayer.'"
