It was narrated from Miqdam bin Ma’dikarib that the Messenger of Allah (ﷺ) said:“The martyr has six things (in store) with Allah: He is forgiven from the first drop of his blood that is shed; he is shown his place in Paradise; he is spared the torment of the grave; he is kept safe from the Great Fright; he is adorned with a garment of faith; he is married to (wives) from among the wide-eyed houris; and he is permitted to intercede for seventy of his relatives.”
