Obligation for a Junub to take Ghusl before praying

Q: I woke up several times while in a state of Janabah (major ritual impurity related to sexual discharge) to find that the time of Salah (Prayer) was about to expire. (Part No. 4; Page No. 145) Should I have performed Tayammum (dry ablution with clean earth) in order not to miss the congregational Salah? Or should I have performed Janabah Ghusl (full ritual bath to cleanse of sexual discharge) even if the due time was missed?

A: You must perform Janabah Ghusl if you want to perform Salah. Allah (Exalted be He) says: O you who believe! When you intend to offer As-Salât (the prayer), wash your faces until His Words: If you are in a state of Janâba (i.e. after a sexual discharge), purify yourselves (bathe your whole body). Therefore, you have to perform Ghusl even if it causes you to miss the due time of Salah, for you are excused for this. Indeed, Taharah (ritual purification) after occurrence of Hadath (ritual impurity that invalidates ablution) is a prerequisite for the validity of Salah. The Prophet (peace be upon him) stated: Allah does not accept the Salah of any of you who become ritually impure, until you perform Wudu'. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
