Performing Wudu' when unable or unwilling to perform Ghusul .

This hadith discusses the importance of ritual purity in Islam. It was narrated from Ibn 'Umar that Umar bin al-Khattab asked the Prophet Muhammad about what one should do if they are in a state of ritual impurity but wish to sleep before performing ghusl, which is the full body ablution required for purification. The Prophet advised that one should perform wudoo, which is an ablution performed for prayer, and then go to sleep. This hadith teaches us that even when we are not able to perform ghusl due to time constraints or other reasons, we must still strive to maintain our spiritual purity by performing wudoo before sleeping. It also emphasizes the importance of maintaining cleanliness and purity according to Islamic teachings.
