Perform ritual ablution before attending congregational prayers such as those on Fridays or during Eid celebrations .

This hadith is about the importance of performing ritual ablution, known as ghusl, before attending the weekly congregational prayer on Fridays. It was narrated by 'Aishah who said that people would come for the Friday prayer in their working clothes and it was suggested to them that they should perform ghusl beforehand. Performing ghusl is a form of purification and cleanliness which is highly recommended in Islam. It involves washing one's entire body with water and can be done at any time during the day or night. It is especially important to do so before attending congregational prayers such as those on Fridays or during Eid celebrations, as it shows respect for God and His house of worship. Additionally, it serves as a reminder to believers that they should strive for purity in all aspects of their lives - physical, mental and spiritual - so that they may be closer to God Almighty.
