... وَتَعَاوَنُوا عَلَى الْبِرِّ وَالتَّقْوَىٰ وَلَا تَعَاوَنُوا عَلَى الْإِثْمِ وَالْعُدْوَانِ ۚ وَاتَّقُوا اللَّهَ ...

In normal circumstances, man carries out God’s commands. But under extraordinary circumstances, he becomes a different man. For example, the occasion arises when somebody’s opposition irritates him. Then one who seemed to fear God in normal circumstances, suddenly changed into one who is fearless of God. Then man forgets the limits of justice and wants to degrade and defeat his opponent in whatever way possible. But this type of revengeful, inimical action is not legitimate in the eyes of God, even if it were in retaliation for being prevented from performing the pilgrimage to the Sacred Mosque in Makkah. If others co-opearate with one who indulges in such oppressive activity this will amount to helping in the commission of a sin. Those who fear God will support others only in righteous deeds. It is the most difficult task in the present world to support those who are on the right path and ignore those who are not on the right path as they have all the wordly glories by their side. But it is by virtue of man’s success in this very task that his fate will be decided.
