It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "As soon as the first drop of the martyr's blood falls, his sins are forgiven; with the second drop he is clothed in the garments of faith; and with the third drop he is married to the wide-eyed maidens of Paradise (al-hur al-'in)."
