When we were sitting in the courtyard of the mosque where the biers were laid down and God’s Messenger was sitting in the midst of us, he raised his eyes to the sky and looked, then lowering his eyes and putting his hand on his forehead he said, “Glory be to God, Glory be to God! What severity has come down!” We said nothing all day and night and experienced nothing but good till the morning. Then I asked God’s Messenger what the severity was which had come down, and he replied, “It has to do with debts. By Him in whose hand Muhammad’s soul is, if a man were to be killed in God’s path then come to life, be killed again in God’s path then come to life, and be killed once more in God’s path then come to life owing a debt, he would not enter paradise till his debt was paid.” Ahmad transmitted it, and there is something to the same effect in Sharh as-sunna.
