Usaamah Ibn Zaid was one of those who had been set free by the Holy Prophet (peace be upon him and his holy progeny), and about whom the Holy Prophet (peace be upon him and his holy progeny) said: He is of those individuals, whom I am particularly fond of and is one of the pious ones from amongst you. Just before his (peace be upon him and his holy progeny) death, he (peace be upon him) appointed Usaamah, despite his young age, as the commander of the army.
It has been reported that one day Usaamah was engaged in prayers in the Prophet’s Mosque near the grave of the Holy Prophet (peace be upon him and his holy progeny). In the meantime, since a person had died, the people approached Marwaan Ibn Hakam, the ruler of Medinah, to lead the funeral prayers for the deceased. He arrived, led the prayers and was on the way out when he observed Usaamah standing near the door of the house of the Holy Prophet (peace be upon him and his holy progeny) still engaged in his prayers. Realizing that he had not participated in the funeral prayers that he had led, a greatly offended Marwan spoke out: You want the people to see you engaged in prayers, isn’t it? He then followed this up with a tirade of abuses and obscene language.
After completing his prayers, Usaamah came up to Marwaan and said: You have hurt me and used obscene and abusive language towards me. I have heard the Holy Prophet (peace be upon him and his holy progeny) say: “God abhors a person, who uses obscene and abusive language. ( Paighambar Wa Yaaraan, vol. 1, pg. 194. )
