Abū Dhar Ghafari (may Allah be pleased with him) relates that he asked the Holy Messenger (may Allah bless and greet him) which of the acts was excellent and of the right standard. The Holy Messenger (may Allah bless and greet him) replied, “To believe in God and to exert in His path.” Abū Dhar again asked which kind of slaves it was better to free? The Holy Messenger (may Allah bless and greet him) said, “Those whose price is high and who are good in their master’s eyes.” Abū Dhar asked if he was unable to do that, and the Holy Messenger said, “Then help some worker or do the work of the man who himself is unable to do it properly.” Abū Dhar again asked if he was unable to do even that. The Holy Messenger (may Allah bless and greet him) said, “Do not give trouble to anyone and that will be an act of charity which will be rewarded.”
Man is the slave of God and God is the Creator, Master and Sustainer of man and everything else in the universe. It is man’s moral obligation to follow the Guidance sent down to the earth in the form of the Qur’an as well as the teachings of God’s Last Messenger, Muhammad (may Allah bless and greet him). Here, in this hadith, the Holy Messenger teaches some of the excellent acts.
Belief in God means to believe in the religion of Islam, His Messengers, His Books, Angels, and the Day of Judgement. Exerting in the path of Allah means to make tireless efforts to establish the Deen on earth and declare that the faith is dearer to a believer than his/her own life. In Arabia, as in the rest of the world, the system of slavery prevailed and Islam had on its programme abolition of slavery and deemed it as the greatest good. To help the needy in the community and to do the work of those who are unable to do it are also virtuous deeds. Even not giving trouble to anyone is an act of charity in the eyes of Islam.
