It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Bilal gives the call to prayer during the night, so keep eating and drinking until Ibn Umm Maktum gives the call to prayer." The narrator says that in fact, Sayyiduna Ibn Umm Maktum (may Allah be pleased with him) was a blind man, he could not see, so he would not give the call to prayer until people said to him, "Give the call to prayer, you have reached the morning."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once the Prophet (peace and blessings be upon him) said: "There is a tree whose leaves do not fall, and it is like a Muslim. Tell me, which tree is that?" People began to think of various trees in the forest. It occurred to me that it could be the date palm tree. After a little while, the Prophet (peace and blessings be upon him) himself said: "It is the date palm tree." I mentioned this to Sayyiduna Umar (may Allah be pleased with him), and he said: "If you had spoken up at that moment, it would have been more beloved to me than such and such things."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: On the Day of Resurrection, a flag will be raised for every deceiver, and it will be announced that this is the deception of so-and-so, son of so-and-so.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) had the trees of Banu Nadir cut down and set them on fire, and on that occasion Allah revealed the verse: "Whatever palm tree you cut down or left standing on its roots, it was by Allah’s command, and so that Allah may disgrace the defiantly disobedient."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) used to say: Do not buy or sell fruit until it ripens. This prohibition is for both the seller and the buyer. Also, the Prophet (peace and blessings be upon him) forbade the sale of Muzabana, which means that a person sells the fruit of his garden—if it is dates, then in exchange for measured dried dates; if it is grapes, then in exchange for measured raisins; if it is crops, then in exchange for a specified measure. The Prophet (peace and blessings be upon him) forbade all these things.
