Explanation

The Prophet (may Allah's peace and blessings be upon him) was sitting with some of his companions including Abu Bakr and ‘Umar. He left them and stayed away for a long time. They feared that someone might have attacked or harmed him. In fact, the Prophet (may Allah's peace and blessings be upon him) was pursued by both the hypocrites and enemies of Islam. So, the Companions (may Allah be pleased with them) got up in alarm, and the first to get up was Abu Hurayrah (may Allah be pleased with him) who went to an orchard that belonged to Banu al-Najjār. Abu Hurayrah started moving around it in order to find an open door, but he did not find any. However, he found in the wall a small opening through which a stream of water passed. He shrank himself and made it through the hole. He found the Prophet (may Allah's peace and blessings be upon him) who said to him: “Is it you, Abu Hurayrah?” He said: 'Yes.' So, the Prophet (may Allah's peace and blessings be upon him) gave him his sandals as a testimony to his truthfulness. He said to him: “Take these sandals of mine, and anyone you meet outside this garden testifying with full certainty that there is none worthy of worship but Allah, give him glad tidings that he will enter Paradise.” The person who says this testimony of faith with full conviction in his heart shall abide by the commands of Allah and avoid His prohibitions. This testimony faith essentially means that there is none truly worthy of worship except Allah. This great meaning entails that one worships Allah alone without associating partners with Him. However, the person who says the testimony by his tongue without conviction in the heart, the testimony will not benefit him.
