Abdullah bin Qais (may Allah have mercy on him) says that I asked Hazrat Aisha (may Allah be pleased with her), "Tell me, did the Prophet (peace and blessings be upon him) perform the ghusl of janabah in the early part of the night or the latter part?" She replied, "Sometimes he would perform ghusl in the early part of the night and sometimes in the latter part." Upon this, I said "Allahu Akbar" and expressed gratitude, "Praise be to Allah who has granted ease in this matter." Then I asked, "Tell me, did the Prophet (peace and blessings be upon him) perform witr in the early part of the night or the latter part?" She replied, "Sometimes he would perform witr in the early part of the night and sometimes in the latter part." Again, I said "Allahu Akbar" and expressed gratitude, "Praise be to Allah who has granted ease in this matter." Then I asked, "Tell me, did the Prophet (peace and blessings be upon him) recite aloud or silently?" She replied, "Sometimes he would recite aloud and sometimes silently." Again, I said "Allahu Akbar" and expressed gratitude, "Praise be to Allah who has granted ease in this matter as well."
