Hazrat Mujahid narrates that Hazrat Yazid bin Shajrah (may Allah have mercy on him) once stood among his companions and said to them: "Blessings of green, red, and yellow are showering upon you in your homes. Tomorrow, when you advance towards the enemy, move forward step by step, because I heard the Messenger of Allah صلی اللہ علیہ وسلم say that when a person takes a step forward to face the enemy, the wide-eyed houris move towards him, and when he retreats, the houris also veil themselves from him. When he is martyred, the first drop of his blood becomes an expiation for his sins. After he is martyred, two houris come to him, clean the dust from him, and say to him, 'Welcome! We are for you.' He replies, 'Congratulations to you, I am for you.'"
