﴿ أَلَآ إِنَّ لِلَّهِ مَا فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ ۖ قَدْ يَعْلَمُ مَآ أَنتُمْ عَلَيْهِ وَيَوْمَ يُرْجَعُونَ إِلَيْهِ فَيُنَبِّئُهُم بِمَا عَمِلُوا۟ ۗ وَٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمٌۢ ﴾

“Oh, verily, unto God belongs all that is in the heavens and on earth: well does He know where you stand and at what you aim! And one Day, all [who have ever lived] will be brought back unto Him, and then He will make them [truly] understand all that they were doing [in life]: for, God has full knowledge of everything.”

The commandment to obey the Prophet of God was directly applicable to his contemporaries and subsequently became applicable to all believing men and women. Those who avoid devoting any efforts to collective affairs may think that they are strengthening their individual interests by not wasting their time on matters which are the concern of the entire community. But any group, which loses its collectivism, makes itself vulnerable to its enemies. The destruction that follows is of a general nature and the harm so caused affects everybody. It does not spare even those who were under the impression that they had made themselves safe by giving full attention to their own matters.
