Sayyiduna Awf bin Malik (may Allah be pleased with him) says: I came to the Prophet (peace and blessings be upon him) during the Battle of Tabuk while he (peace and blessings be upon him) was in a tent of leather. He (peace and blessings be upon him) said: "Count six signs before the Hour: my death; the conquest of Bayt al-Maqdis; countless deaths, as when sheep suddenly die; the abundance of wealth, to the extent that a man will be given a hundred dinars yet he will remain displeased; a tribulation will appear that will enter every house of the Arabs; and a truce will take place between you and the Romans, but they will break the covenant, and they will come against you under eighty (80) banners, under each banner twelve thousand."
(b) Al-Walid says: We discussed this hadith with one of the shaykhs of Madinah regarding his words "then the conquest of Bayt al-Maqdis", and the shaykh said: Sa'id told me from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he used to narrate this hadith from the Messenger of Allah (peace and blessings be upon him), and in place of "the conquest of Bayt al-Maqdis" he would say: "the flourishing (populating) of Bayt al-Maqdis."
