Sayyiduna Yusuf bin Abdullah bin Salam (may Allah be pleased with them both) narrates from his father: We were walking with the Messenger of Allah (peace and blessings be upon him) when the companions asked, "Which deed is the best?" He (peace be upon him) said, "Faith in Allah, striving in His path, and an accepted Hajj." Then a voice was heard: "I bear witness that there is no god but Allah, Muhammad is the Messenger of Allah." So he (peace be upon him) said, "And I also bear witness, and whoever says this from the heart is free from shirk (associating partners with Allah)."
