Allah says: Then We revealed to Moses: Strike the sea with your staff.
Allah says: Then We revealed to Moses: Strike the sea with your staff. So it had cloven asunder, and each part was like a huge mound. Qur'an, 26:63 And when Moses prayed for drink for his people, We said: Strike the rock with your staff So there gushed from it twelve springs . Qur'an, 2:60 It is no wonder then that the Messenger of Allah (S) asked az-Zubayr to give him that iron-tipped stick to seek the blessing in it, or it could be to teach people that seeking blessing is permissible in Islam.
This possibility is too strong, especially when we know that all the caliphs after the Prophet (S) had asked for this stick, which moved from one to another until finally it came to Abdullah ibn az-Zubayer, for it was his father’s heritage. We find in the Holy Qur'an many references to seeking blessing in things that were related to prophets and messengers. It has been said in the Qur'an: He said: What was then your case, O Samiri?
He said: I perceived what they perceive not, so I seized a handful from the footsteps of the messenger, and then threw it in. Thus, my soul commended to me . Qur'an, 20:95-96 Perhaps Samiri perceived what the rest of companions, did not perceive when he seized a handful from the earth that the Prophet had stepped on, or which might have achieved some miracles.
So he thought that Moses was a great magician and the miracles he showed to people were just magic that whoever had means to do it, could do. Therefore, he threw the handful of earth and his soul incited him to take the Children of Israel back to worship the calf. The story confirms what we have said that he showed some charismata and miracles to the Israelites until they were deceived and they followed him.
We find other references in the Holy Qur’an to the seeking of blessing and cure by the belongings of the prophets. Allah says in the Sura of Yousuf: Take this my shirt and cast it on my father’s face, he will (again) be able to see, and come to me with all your families. And when the caravan had departed, their father said: Most surely I perceive the scent of Yousuf, unless you pronounce me to be weak in judgment. They said: By Allah, you are most surely in your old error.
So when the bearer of good news came, he cast it on his face, so forthwith he regained his sight. He said: Did I not say to you that I know from Allah what you do not know .
