Hazrat Abu Huraira (may Allah be pleased with him) says that I heard Hazrat Abu Bakr Siddiq (may Allah be pleased with him) saying on this pulpit of the Messenger that on this very day last year I heard the Prophet (peace and blessings be upon him) saying this, and while saying this he began to weep and tears flowed from his eyes. After a little while, he said that I heard the Prophet (peace and blessings be upon him) saying that after the word of Tawheed and sincerity, you have not been given any blessing greater than well-being, so ask Allah for well-being.
