Every Human being on this planet, whether rich or poor, black or white, proletarian or bourgeoisie, king or beggar, Muslim or non-Muslim, is in search of peace. The important element that humans need the most for living is mental peace.
Inner peace lies in two major things: in serving humanity and in the remembrance of Allah. Islam has put great emphasis on both of these things. It would not be wrong to say Islam is the religion of peace and tranquility. Islamic teachings lead to inner peace if people follow them as per the guidance of the Quran and Sunnah. As Allah says in Surah Ma’idah, verses 15-16:
يَـٰٓأَهْلَ ٱلْكِتَـٰبِ قَدْ جَآءَكُمْ رَسُولُنَا يُبَيِّنُ لَكُمْ كَثِيرًۭا مِّمَّا كُنتُمْ تُخْفُونَ مِنَ ٱلْكِتَـٰبِ وَيَعْفُوا۟ عَن كَثِيرٍۢ ۚ قَدْ جَآءَكُم مِّنَ ٱللَّهِ نُورٌۭ وَكِتَـٰبٌۭ مُّبِينٌۭ ١٥
يَهْدِى بِهِ ٱللَّهُ مَنِ ٱتَّبَعَ رِضْوَٰنَهُۥ سُبُلَ ٱلسَّلَـٰمِ وَيُخْرِجُهُم مِّنَ ٱلظُّلُمَـٰتِ إِلَى ٱلنُّورِ بِإِذْنِهِۦ وَيَهْدِيهِمْ إِلَىٰ صِرَٰطٍۢ مُّسْتَقِيمٍۢ ١٦
“O People of the Scripture! Now hath Our messenger come unto you, expounding unto you much of that which ye used to hide in the Scripture, and forgiving much. now hath come unto you light from Allah and plain Scripture, Whereby Allah guideth him who seeketh His good pleasure unto paths of peace. He bringeth them out of darkness unto light by His decree, and guideth them unto a straight path." — M. Pickthall”.
[Surah Al-Maidah:15-16]
