SHAFAQNA – Sheikh Mohammad ibn Ali Ameli in the book of Tohfatul Talib from the book of Masabih which is one of the books of Ahlul Sunnah has narrated from Zaid ibn Arqam who said: One day the Prophet of Allah (SWT) had seven stones in his hand, and suddenly the stones started praising God. Then, the Prophet (PBUH) placed the stones in the hand of Imam Hassan Mojtaba (AS) and then in the hand of Imam Hussain (AS), and again the stones praised God in their hands. Some of the companions, who were present, took the stones in their hands but the stones were silent. They asked: What is the reason for this? The Prophet (PBUH) replied: Because these stones do not praise (God) except in the hands of the Prophet (PBUH) and his successors (Wasi) [1].
