Anas (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: ''If Allah willed to do good to His slave, He expedites his punishment in the life of this world, and if He willed to do ill to His slave, He withholds the punishment for his sins until He comes with all his sins on the Day of Resurrection."
The Prophet (may Allah's peace and blessings be upon him) says that the sign that Allah wants good for His slave is to expedite the punishment for his sins in this world, so that the slave leaves the world without a sin to be punished for on the Day of Resurrection. Those who are reckoned for their deeds in the life of this world will go through a light questioning in the Hereafter. Also, the sign that Allah wants bad for a slave is that He does not punish him immediately in the life of this world until he comes with a full load of sins for which he receives due punishment on the Day of Resurrection.
