It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Islam is that you worship Allah and do not associate anything with Him, establish the prayer, pay the zakah, fast in Ramadan, perform Hajj to the House (of Allah), enjoin good, forbid evil, and greet your family with salam. So whoever falls short in any of these has abandoned that share of Islam (which was due from him), and whoever abandons all of them has turned his back on Islam." This hadith is like the first hadith in its soundness and reliability.
