So, one bounty that the saints are blessed with is that they see the angels of God. The life of the hereafter is based completely on faith. However, a righteous person beholds the hereafter in the present life. It is in this very life that they find and witness God, and He speaks with them. So if a person is not blessed with such a state of affairs, his death and passing on from this world is not a promising prospect. A certain saint is reported to have said that a person who has not been blessed to experience even one true dream all their life is to be met with a perilous end. The Quran also says that this is the hallmark of a believer. Take heed! One who does not possess this sign is bereft of righteousness. So, we all ought to pray that this condition is fulfilled in us. May Allah the Exalted bless us with the grace of revelation, dreams and visions. For these are characteristic of a believer, and thus, should exist in us.
