The Final Messenger ﷺ said, "Islam is that you should testify that there is no deity worthy of worship except Allah and that Muhammad is His Messenger (ﷺ), that you should perform salah (ritual prayer), pay the zakah, fast during Ramadan, and perform Hajj (pilgrimage) to the House (the Ka`bah at Makkah), if you can find a way to it (or find the means for making the journey to it)." (Bukhari)
