The Prophet (peace and blessings of Allah be upon him) was indeed the best teacher and nurturer for his Ummah. He taught them by both words and actions. Among what he taught were the rulings related to purification and all that pertains to it at all times—what is permitted therein and what is not.In this Hadith, `A’ishah (may Allah be pleased with her) said: "The Prophet (peace and blessings of Allah be upon him) would spend the night in a state of major ritual impurity (Junub)"—that is, he would remain throughout the night in the state of (Junub) and would delay performing the ritual bath (Ghusl). "Then Bilal (may Allah be pleased with him) would come to inform him of the prayer"—meaning: he would inform him that it’s time for the Fajr prayer. "So he would get up and perform the ritual bath (Ghusl)"—that is, he would perform (Ghusl) from (Janabah) after the Adhan of Fajr. She said: "I would see the water dripping from his head"—that is, she would see the water running down from his hair as a result of the (Ghusl). "Then he would go out, and I would hear his voice in the Fajr prayer"—meaning: he would go out after performing (Ghusl), and she would hear his voice reciting in the Fajr prayer.Another narration clarified that this action of the Prophet (peace and blessings of Allah be upon him) occurred during Ramadan and outside of it. If it was in Ramadan, then the Prophet (peace and blessings of Allah be upon him) would begin the fast in the state of (Junub) and would not break his fast. In this action of his is a clarification of the permissibility of delaying Ghusl until the time of Fajr or shortly after it. `A’ishah (may Allah be pleased with her) was asked: "How would the Prophet (peace and blessings of Allah be upon him) act regarding Janabah?" Did he perform Ghusl before going to sleep, or did he sleep before performing it? She said: “He (peace and blessings of Allah be upon him) used to do all of that—sometimes he would perform Ghusl and then sleep, and sometimes he would perform minor Wudu’ and then sleep.”This Hadith indicates the leniency of the Shari`ah in matters related to purification from major ritual impurity (Janabah). It also affirms the permissibility of delaying Ghusl until Fajr, and that Janabah does not invalidate fasting if one is in that state before Fajr and intends to fast..
