A boy of about 12 years old was sitting in Masjid-e-Nabawi listening to a discourse (Bayaan) by Rasulullah (Sallallahu alaihi wasallam). The Bayaan had a profound effect on the heart of the boy. He went to his uncle, Jullaas Bin Suwaid who was a Munaafiq who performed Salaah with the Sahaabah and conducted himself like a Muslim.
The boy came and said to his uncle, “O My uncle! I heard Rasulullah (Sallallahu alaihi wasallam) informing us about the Impending Hour (of Qiyaamah). It is as if I am seeing Qiyaamah with my eyes.”
The Munaafiq Jullaas replied, “Child! By Allah! If Muhammad is true, then we all are worse than donkeys.” In other words, Muhammad (Sallallahu alaihi wasallam) is false.
The colour of the boy changed. He was shocked to hear such abuse and denial of Rasulullah (Sallallahu alaihi wasallam) by his uncle whom he thought was a sincere Muslim.
In consternation, rebuking his uncle, the boy said, “O Uncle! By Allah! You were the most beloved to me. By Allah! Now you are the most-hated to me. O uncle! I am between two options. Either I betray Allah and His Rasool by not informing him of what you have said, or I inform him, and let things take their course.”
The boy informed Rasulullah (Sallallahu alaihi wasallam) of the Nifaaq of his uncle, but he (the uncle) denied the claim of his nephew. Allah Ta’ala sent Wahi to confirm the veracity of the boy’s claim. Love for Allah and His Rasool and obedience do not tolerate that family ties be sustained with the enemies of Allah and those who abuse Rasulullah (Sallallahu alaihi wasallam). This boy is Umair Bin Sa’d (Radhiyallahu anhu).
Hazrat Umar (Radhiyallahu anhu) had appointed him the governor of Hims.
