Abu Basrahh Ghifari reported: The Messenger of Allah (ﷺ) led us in the 'Asr prayer at (the place known as) Mukhammas, and then said: This prayer was presented to those gone before you, but they lost it, and he who guards it has two rewards in store for him. And no prayer is valid after till the onlooker appears (by onlooker is meant the evening star).

Abu Dharr (RA) reported Allah's Messenger (ﷺ) as saying: You would soon conquer Egypt and that is a land which is known (as the land of al-qirat). So when you conquer it, treat its inhabitants well. For there lies upon you the responsibility because of blood-tie or relationship of marriage (with them). And when you see two persons falling into dispute amongst themselves for the space of a brick, than get out of that. He (Abu Dharr) said: I saw Abdul Rahman bin Shurahbil bin Hasana and his brother Rabi'ah disputing with one another for the space of a brick. So I left that (land).
