It is narrated from Sayyiduna Abu Ruhm al-Sama'i (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Among the worst of thieves is he who steals the tongue of the ruler; among the greatest of sins is that a person seizes the wealth of a Muslim without right; among good deeds is visiting the sick, and part of completing the visit is that you place your hand on him and ask him how he is; among the best forms of intercession is that you intercede between two people in marriage until you bring them together; among the dress of the prophets is that the shirt is put on before the trousers; and among the things through which acceptance is hoped for at the time of du'a is sneezing."
