Conveyer of a Message
There is an incident which took place during the Battle of Uhud, which, although it has been previously narrated, I will briefly mention it again.
After the battle, the Holy Prophet (sa) instructed Hazrat Ubayy (ra) bin Kaab to go and assess the conditions of those injured. As he went searching, he came across Hazrat Saad bin Rabi (ra) who had been fatally wounded and was breathing his last. Hazrat Ubayy (ra) asked him if he wished for him to convey any message to his relatives and loved ones. Hazrat Saad (ra) smiled and replied that he was hoping a Muslim would walk by so that he could pass onto him his message. He then stated, “Place your hand in mine and promise me that you will certainly convey my message.”
His message was, “Convey my greetings of peace [salam] to my fellow Muslim brethren and tell my people and relatives that the Holy Prophet (sa) is the most excellent trust which Allah the Almighty has granted to us and we protected this trust with our very lives. Now I depart, but I hand over the responsibility of protecting this trust over to you. Let it not be the case that you show negligence in its protection.”
