Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah (PBUH) said, "Beware of suspicion, for suspicion is the worst of false tales. Do not look for other's faults. Do not spy one another, and do not practise Najsh (means to offer a high price for something in order to allure another customer who is interested in the thing). Do not be jealous of one another and do not nurse enmity against one another. Do not sever ties with one another. Become the slaves of Allah, and be brothers to one another as He commanded. A Muslim is the brother of a Muslim. He should neither oppress him nor humiliate him. The piety is here! The piety is here!'' While saying so he pointed towards his chest. "It is enough evil for a Muslim to look down upon his Muslim brother. All things of a Muslim are inviolable for his brother in Faith: his blood, his wealth and his honour. Verily, Allah does not look to your bodies nor to your faces but He looks to your hearts and your deeds.'' Another narration is: "Do not feel envy against one another; do not nurse enmity; do not spy on one another and do not cheat one another. Be Allah's slaves, brethren to one another.'' Another narration is: "Do not have estranged relations with one another. Do not nurse enmity and do not feel envy against one another. O Allah's worshippers! Be brothers!'' Another narration is: "Do not estrange mutual relations and do not intervene into the transaction which is likely to be settled with another person.'' [Muslim].
We all are human & we all have emotions & its our duty to respect each other & spread happiness because no one knows tomorrow what will happen
