Assalmu alaikum

Abdullah lIbn 'Umar Radiyallahu 'anhuma narrates that in reply to a question of Jibr'ail about Islam Rasullullah Sallallahu 'alaihi wasallam said: Islam is bearing witness that none is worthy of worship but Allah and that Muhammad is the Messenger of Allah, and that you establish Salat, and give Zakat, and perform Haj to the House of Allah and perform Umrah, and take bath after Janabah and perform complete Wudu, and Saum in Ramadan. Jibr'ail then said: If I do all of that, then am l a Muslim? He replied: Yes. Jibr'ail then confirmed: You have spoken the truth. (Ibn Khuzaimah)
