“Once I was in the presence of Abu ‘Abdillah (a.s.) that an old man came and said, ‘O Abu ‘Abdillah (a.s.) I complain to you against my sons for their failing to maintain good relations with parents and against my brothers for their injustice to me during my old age.’ Abu ‘Abd Allah (a.s.) said, ‘O you, for truth there is a kingdom and for falsehood there is a kingdom. Each of them is humiliated in the kingdom of the other. The least that a believer may suffer in the kingdom of falsehood is the failure of his children to maintain good relations with parents, and injustice from his brothers. Any believer who may receive comfort in the kingdom of falsehood, for this he faces suffering before his death, either in his physical health, his children or his property until Allah purifies him from what he has received in the kingdom of falsehood and will expand his share in the kingdom of truth. Exercise patience and be happy.’”
