Stalk of the female or fruiting inflorescence
The ‘urjūn of the nakhl (palm tree) is the main inflorescence’s stalk; it carries numerous long peduncles, each of which bears many female flowers, which later develop into fruits. The ‘urjūn is yellow, flattened, broad, woody and curved. When an ‘urjūn becomes old, it turns fine, curved and yellow hence it is named ‘Urjūn Qadim in the Holy Qur’an. By contrast, the early Arabs call the peduncle of the male inflorescence ‘atal.
The term ‘urjūn is mentioned once in the Holy Qur’an. Allah the Most Merciful, the Most Compassionate says: “And the Moon - we have measured for her mansions (to traverse) until she returns like the old (and withered) lower part of a date-stalk.” Surat Ya Seen, verse 39.
Narrated Ubadah ibn as-Samit: We came to Jabir ibn Abdullah who was sitting in his mosque. He said: The Messenger of Allah (PBUH) came to us in this mosque and he had “urjūn” a twig of date-palm inflorescence of the kind of Ibn Tab. He looked and saw phlegm on the wall towards qiblah. He turned to it and scraped it with the twig. He then said: Who of you likes that Allah turns His face from him? He further said: When any of you stands for praying, Allah faces him. So he should not spit before him, nor on his right side. He should spit on his left side under his left foot. If he is in hurry (i.e. forced to spit immediately), he should do with his cloth in this manner. He then placed the cloth on his mouth and rubbed it off. He then said: Bring perfume. A young man of the tribe stood and hurried to his house and returned with perfume in his palm. The Messenger of Allah (saws) took it and put it at the end of the twig. He then stained the mark of phlegm with it. Jabir said: This is the reason you use perfume in your mosques. Sunan Abi Dawud, book of Prayer.
