Sayyiduna Ibn Umar (may Allah be pleased with them both) says that washing urine from a garment was prescribed seven times. The Prophet (peace and blessings be upon him) kept going back and having it eased, until washing urine from a garment was set at three times.

Narrated Abdullah ibn Umar: There were fifty prayers (obligatory in the beginning); and (in the beginning of Islam) washing seven times because of sexual defilement (was obligatory); and washing the urine from the cloth seven times (was obligatory). The Messenger of Allah ﷺ kept on praying to Allah until the number of prayers was reduced to five and washing because of sexual defilement was allowed only once and washing the urine from the clothe was also permitted only once.
Shaykh Umar Farooq Saeedi
Benefits and Issues: ➊ The ruling is likewise that in the ritual bath (ghusl) of major impurity (janabah), it is obligatory to pour water over the body once. Similarly, washing the garment is also required only once.
