It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once someone asked the Prophet Muhammad (peace and blessings be upon him) about this issue: If a person finds such water in the wilderness where animals and beasts also come, can ablution be performed with it?

He went to the service of the Prophet (peace and blessings of Allah be upon him) and wanted to consult him about it. So he said: O Messenger of Allah! A piece of land from Khaybar has come to me as my share, and I have never received wealth better than this. What do you command me regarding it? The Prophet (peace and blessings of Allah be upon him) said: "If you wish, keep its original property with you and give its benefits as charity." So Sayyiduna Umar (may Allah be pleased with him) dedicated it for the poor, close relatives, slaves, warriors, travelers, and guests, and said that there is no harm for the caretaker of this land to eat from it in a good manner or to feed a friend from it, provided he does not seek to accumulate wealth from it.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Do not intend to pray at the time of sunrise or sunset, because the sun rises between the two horns of Satan. When the edge of the sun begins to rise, do not pray until it becomes fully apparent, and similarly, when the edge of the sun begins to set, do not pray until it has completely set."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) explained this verse, "When people will stand before the Lord of the worlds," by saying that at that time people will be standing, submerged in their sweat up to half of their ears.
