According to the Prophet's recommendation, when a person newly converts to Islaam, he should be advised to take a ghusl. Qays ibn'Aasim said, "I came to the Prophet (sallallaahu `alayhi wa sallam) in order to accept Islaam and he told me to take a ghusl with water and Sidr (Lote-tree leaves). (Sunan Abu Dawud, vol. 1, p.93, no. 355, an-Nasaa'ee, at- Tirmithee and Ahmad, and authenticated in Irwaa al-Ghaleel, vol.1, p.163-4, no.128).
- Jumu'ah Prayer
In the early days of Islaam, taking a ghusl for the Friday congregational prayers was compulsory. Sa'eed al-Khudree quoted Allaah's Messenger (sallallaahu `alayhi wa sallam) as saying, "Taking a ghusl on Friday is compulsory for everyone who has reached puberty." (Sahih Muslim vol. 2, pp.163-4 no. 1838) ‘Aa'ishah related that people would come to Friday prayer from their houses in neighbouring villages dressed in dusty wollen garments which emitted bad odours. One of them came to the Messenger of Allaah (sallallaahu `alayhi wa sallam) while he was in ‘Aa'ishah's home and the Messenger of Allaah said to him, "It would be good if you cleaned yourself on this day." Prophet Muhammad (sallallaahu `alayhi wa sallam) strongly recommended that Muslims who attend the Friday congregational prayer take a complete Islaamic bath (ghusl). However, the obligation was later reduced to a strong recommendation. Samurah quoted Allaah's Messenger(sallallaahu `alayhi wa sallam) as saying, "Whoever makes wudoo on Friday, it is good [for him], but if ghusl is taken, it is better." (Sunan Abu Dawud vol.1, p. 93,
