Chapter 33: Verse 23
"Among the believers are men who are true to their covenant with Allah. Of them some have fulfilled their obligations and some of them are still waiting, but they have never changed in the least."
The above Quranic verse captures the essence of the believers' covenant with Allah. It signifies the Islamic movement, the call to truth and the believers' unwavering and single-minded commitment to Islam. Implicit in it is also the assertion that the believers are ever ready to sacrifice all that they have for this cause.
Islam is synonymous with a pledge. It is to be seen how many of us are true to this pledge, for men are liable to forget their oaths. We must remind ourselves of the glorious examples of the Prophet's Companions. After professing Islam they paid no heed to praise or criticism of fellow human beings. Their only concern was their loyalty to Islam.
Our verbal profession of Islam is meaningless. We may bear Muslim names and our way of life may contain some Islamic elements. We may occasionally visit the mosque. Our main duty as believers, nonetheless, is to be true to our pledge to Allah. In our beliefs, acts of worship, conduct, dealings, way of life, social relations, marital ties, family and neighbourhood relationships and in every human activity we must behave as Muslims. Our commitment must be to divine laws.
Among the many billions of Muslims, some are specified in the above verse as being believers with firm resolve. Praise is heaped on them for their discharging their obligations to Allah. Then mention is made of those among them who have completed their appointed term and returned to Allah. They will be lavishly rewarded. Those still alive look forward to divine rewards and are true to their covenant. They have not changed their commitment in any degree.
