It is narrated from Hazrat Salman (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Spending one day in preparation for jihad in the way of Allah is better than fasting for a month and worshipping for a month. Whoever passes away while preparing for jihad will be saved from the torment of the grave, and the reward for his good deeds will continue until the Day of Resurrection.
