Thauban said that when "And those who hoard gold and silver" 1. came down they were with the Prophet on one of his journeys. One of his companions said, "It has come down about gold and silver. Would that we knew what property is best so that we might get it!" He replied, "The best property is a tongue which makes mention of God, a grateful heart, and a believing wife who helps a man with his faith."
1. Qur’an, ix, 34.
Ibn ‘Umar reported God’s messenger as saying, "Do not speak much without mentioning God, for much talk without mention of God produces hardness of heart, and the one who is farthest from God is he who has a hard heart."
Abu Sa'id said that Mu'awiya went out to a circle in the mosque and asked them what had made them sit together. When they replied that they had sat down to remember God, he said, "I adjure you by God, has nothing else made you sit together?" On their reply that there was certainly no other cause he said, "I did not adjure you because I suspected you. No one in my position with relation to God’s messenger has fewer traditions from him than I have; but God’s messenger went out to a circle of his companions and asked them what had made them sit there, and when they replied that they had sat together to remember God and praise Him for guiding them to Islam and bestowing favour on them he said, ‘I adjure you by God, has nothing else made you sit together?’ On their replying that there was certainly no other cause he said, ‘I did not adjure you because’ I suspected you, but Gabriel came to me and told me God is speaking proudly of you to the angels’."
Umm Habiba reported God's messenger as saying, "Everything a son of Adam says counts against him and not in his favour, except recommending what is good, prohibiting what is objectionable, or making mention of God."
