Prayer is one of the five pillars of Islam

Talha bin Ubaidullah narratives ra., He said:
Someone from the Najed matted hair came to the Messenger of Allah. We hear the echo of his voice, but we did not understand what he was saying until he approached the Prophet. and ask about Islam. Then the Messenger of Allah. He said: (Islam is) pray five times a day and night. The man asked: Are there any other prayers which obliged me? Prophet. answer: No, unless you want to pray circumcision. Then the Messenger of Allah said: (Islam also) fasting during Ramadan. The man asked: Are there any other fasting obliged me? Prophet. answer: No, unless you want to do fasting circumcision. Then the Messenger of Allah. continues: (Muslims also) zakat fitrah. The man asked: Are there any other charity obliged me? Prophet. answer: No, unless you want to give alms. Then he was gone and said: By Allah, I am not going to add this duty and will not reduce it. Hearing that, the Prophet. He said: He is a lucky man if true what he said. (Saheeh Muslim, # 12)
