Reminding the Believers of the Bounty of the Message and Islam
Allah reminds His believing servants of His bounty by legislating this glorious religion and sending them this honorable Messenger. He also reminds them of the covenant and pledges that He took from them to follow the Messenger , support and aid him, implement his Law and convey it on his behalf, while accepting it themselves. Allah said,
(And remember Allah's favor upon you and His covenant with which He bound you when you said, "We hear and we obey.") This is the pledge that they used to give to the Messenger of Allah ﷺ when they embraced Islam. They used to say, "We gave our pledge of obedience to the Messenger of Allah to hear and obey, in times when we are active and otherwise, even if we were passed on for rights, and not to dispute leadership with its rightful people." Allah also said,
The subject of the first of the three verses given above has appeared earlier in Surah al-Nis-a' in almost the same words. The only difference is that the arrangement of words there (4:135) was: كُونُوا قَوَّامِينَ بِالْقِسْطِ شُهَدَاءَ لِلَّـهِ while, here (5:8), it has been said: كُونُوا قَوَّامِينَ لِلَّـهِ شُهَدَاءَ بِالْقِسْطِ (be steadfast for Allah as witnesses for justice). A delicate reason for the alternation in words appearing earlier and later in these two verses has been given by Abu Ha-an in his Tafsir Al-Bahr al-Muhit a gist of which is given below.
There are usually two causes which hold people back from doing justice and then make them do the unjust and the oppressive. The first one is taking the side of your own self, or that of your friends and relatives. Enmity with someone is the other cause. The verse in Su-rah al-Nis-a' is addressing itself to the first subject while this verse of Surah al-Ma'idah is oriented to the other.
Faith is the vow which binds God and His subject. The subject vows that he will remain God-fearing in his life in this world, and God guarantees that He will be His subject’s guardian in this world and in the Hereafter. God’s subject has to prove his fulfillment of his vow in two ways. First, he should become steadfast on the path of God. On every occasion his lifestyle should give the response which is expected of a subject to his Lord. When he observes the universe, his mind should be filled with the realisation of God’s glories and powers. When he looks at himself, he should realise that his existence is entirely due to God’s grace and His mercy. If his emotions erupt, they should erupt for the sake of God. If his attention is focused on anybody, it should be on God. His love should be for God. His fears should be linked with God. The remembrance of God should be uppermost in his mind. He should be given to prayer and obedience to God, and should spend his assets for the cause of God. In devoting his life to God, he should feel pleasure. The second condition for the fulfillment of the vow of God’s subject is that his dealings with his fellow-beings should be based on justice and fair play. Justice means meting out to a person that treatment which he actually deserves—no more and no less. In his dealings he should follow the dictates of justice and not his desires. He should be bound by this principle to the extent that he should adhere to justice even when dealing with his enemies; even when grievances and bitter memories are apt to divert him from the path of justice.
