Islam is a religion of mercy and compassion towards people, and seeks to make things easy for them. One example of that is the fact that purifying oneself from major impurity after becoming junub in order to resume doing acts of worship is a ruling with which one must comply; janabah is a shar‘i description, and it does not prevent one from dealing with other issues of daily life. In this hadith, ‘Abdullah ibn ‘Umar (may Allah be pleased with him) narrates that ‘Umar asked the Prophet (blessings and peace of Allah be upon him) whether a person could go to sleep when he is not in a state of purity because he is junub. The word junub refers to anyone who emits maniy (semen) or has intercourse with his wife; it is so called because he must avoid (ijtinab) prayer and other acts of worship until he has purified himself. The Prophet (blessings and peace of Allah be upon him) told him that if he wanted to go to sleep when he was in a state of janabah, it was better for him to do wudu’ and wash his penis, but he did not have to do a complete ghusl. According to a report narrated by Muslim, he said: “Yes; let him do wudu’ then go to sleep, and then he does ghusl when he wants to.” Thus the time of doing ghusl is based on his choice, and ghusl becomes necessary if he wants to do some act of worship, especially when the time for prayer comes; in that case he must do it before the time for that prayer ends. This hadith indicates that one may ask about matters of concern, and should not feel too shy to ask. It also indicates that janabah is a shar‘i description, and is not to be taken literally..
