Does the one who gives a rosary (subḥah) get the same reward as the one who uses it for tasbīḥ (glorification), or the reward for assisting in a good deed?

The reward for an act of worship is for the one who performs it. And whoever calls to guidance or points to good, will have a reward like that of its doer. Gifting a rosary falls under the category of pointing to good, even though it is better to count tasbeeh with the fingers, emulating the Prophet, peace and blessings be upon him. The permissibility of using a rosary for tasbeeh is established.
