When a quarrel intensifies, when its roots go deeper, its thorns become branches and branches increase in number, then the freshness of the fruits of faith is adversely affected. Softness, sympathy, satisfaction and peace, which are encouraged by the Islamic teachings, receive a setback. Performance of worship loses its righteousness, while the self get no benefit from it.
Many a time mutual quarrels perturb the persons who claim to be wise. When this happens, they take recourse to lowly and superficial things, and sometimes indulge in dangerous acts which only increase difficulties and bring troubles. When a man is displeased, his eyes become prejudiced and ignore the camel and object to gnat. Such eyes do not appreciate the beauty of the peacock, for they only see its ugly feet and claws. If a slight defect is present, it turns the molehill into a mountain. And sometimes the internal rancour and jealousy affect them so badly that no hesitation is felt in inventing imaginary stories. Islam disapproves of all these manifestations of ill feeling and advises to abstain from them. It declares their avoidance as the most virtuous form of worship.
The Prophet said:
“Listen, may I not tell you something more important than salat, fasting and charity?” The people requested him to do so. He said: “To keep the mutual relationship on the right footing, because the defect in the mutual relationship is a thing which shaves a thing clean. I do not mean that it shaves the hair, but that it shaves (removes) the religion.” (at-Tirmidhi)
Many a time Satan is not able to persuade wise men to worship idols, but since he is very keen on misguiding and ruining men, he manages to succeed in driving them away from God, so much so that these wise men become more indifferent in respecting the rights of God than the idolaters themselves. The best method adopted by the devil for this purpose is to sow the seeds of enmity in the hearts of the people. When this enmity develops into a fire and open hostilities result, he enjoys the scene. This fire burns man’s present and future into ashes and totally destroys their relationship and virtues.
The Messenger of Allah said:
“The Satan has been disappointed that he would not be worshipped in the Arabian Peninsula, but he has not been disappointed from kindling the fire of fighting among the people.” (Muslim)
It means that when wickedness takes roots in the hearts, when people start hating love and brotherhood, and when these are destroyed, people then revert to cruelty and enmity, and break all those relations and links which Allah has commanded to be kept; thus spreading corruption on this earth.
