Yes. According to the Buddha, the Buddha Dharma covers three successive periods: First, the Period of True Dharma (Saddharmma), i.e. the period of arising and flourishing of Buddhism; Second, the Period of Image Dharmma, i.e. the evolution period, in which the Buddha’s images began to appear; Third, the Period of Termination or the period of decay. The Buddha even discussed the circumstances of Dhamma extinguishing in future. “All dhammas are impermanent”, Buddhism itself is no exception. (From Essentials of Buddhism: Questions and Answers)
