Abdullah bin Masud (may Allah be pleased with him) relates Allah’s Messenger (may Allah bless and greet him) as saying: Whom do you count as Raqub among you? They (his Companions) said: One who has no children (the children are born unto him but they do not survive). Thereupon he (the Holy Messenger) said: He is not a Raqub; Raqub is one who does not find his child as the forerunner (in the Paradise). He then said: Whom do you count as a wrestler among you? We said: He who wrestles with persons. He said: No, it is not he but one who controls himself when in a fit of rage.
What the Holy Messenger (may Allah bless and greet him) wanted to bring home to his Companions was that the words Raqub and Sura’ah carry deep spiritual meanings from the point of view of a person whose children do not survive in this life and thus he is sad and morose because of the demise of his offspring. But in the domain of religion and spirituality Raqub is one who does not face the pang of the bereavement of his children or does not show patience at such bereavement. There is no cause of moroseness and sadness for a Raqub from the religious point of view as he is going to benefit by the demise of his child in the Hereafter, provided he shows patience at the death of his child or children. If the child who dies is minor, he would be an intercessor for him in the Hereafter; and if the child is young and the parent shows patience at his death, this act of his would be a source of reward and benefit for him in the life after death.
Similarly, the word wrestler has a deep spiritual meaning other than that in which this word is used in our daily life. The wrestler is not one who is strong and is able to overthrow another person is a bout, but one who has control over his anger and is able to counteract successfully the attacks of Satan.
