Tradition 6

شيعَتُنَا الّذينَ اِذا خَلَوا ذَكَرُوا اللّهَ كَثيرًا.

Imam as-Sadiq (‘a) said: “Our true followers are those who, when they are alone, remember Allah abundantly.” (That is, they avoid committing vices in private where there is no barrier for them to commit sin by the mere remembrance of Allah.)
