Will the person at whose hands another embraced Islam receive a reward like that of a martyr if the one who embraced Islam at his hands is martyred?

The hadith (definition) indicates the virtue of guiding to good and assisting those who do good, and that whoever guides to good will receive a reward similar to that of the doer of the good deed. It is not necessary for the amount of their reward to be equal. This can be achieved by offering aid to a mujahid with provisions, weapons, or by caring for his family, or by guiding to someone who can transport him. A Muslim should not feel secure from Allah's plan and should persevere in obedience until he meets Allah.
