Hazrat Khalid bin Waleed (may Allah be pleased with him) says that there is no night on the face of the earth more beloved to me, in which I receive the good news of a son and a bride is sent to me whom I love, than that night which is full of hardship, which I spend with a group of Mujahideen, and in the morning I lead them to attack the enemy. Therefore, jihad is obligatory upon you.
